Equally, when we think of grains, a familiar image that comes to mind is children playing on the beach, building sandcastles (or in good Dutch tradition, perhaps a dam to keep the sea out). They know you must use moist sand to make nice figurines. They also know that when you dig too deep on the beach, that water may come in and wreck your castle. You have to know your stuff when you start building things. Parents stimulate these construction experiments by supplying the building materials for some serious out-of-the-box thinking. The children start small, developing new, and intriguing concept cars (Figure 1), and then move on to bigger ideas and perhaps they build robots (Figure 2). A concept car made of Duplo blocks. Some people might say there is a screw loose inside if you occupy yourself with carton robots (I designed the robots for a children’s vacation camp ??). Still, the fascination with building beautiful things remains at all ages. A while ago, my neighbor asked me to take a look at this impressive tower built of Anker stones without using any glue (Figure 3, ). But as with the Anker tower, to have a stable structure, you need to keep paying attention to detail. If you have ever built anything yourself, you know how important it is to use the right components and ensure that all the parts fit together. Such materials are typically being deliberately developed for certain purposes by mixing components and then treating them just so, but sometimes also found by accident. And of course, it is not only the composition of a material that defines its properties, it is also the microstructure that makes a material suitable for specific applications. When you take care to pick the proper starting material for your product, you can successfully build something. However, sometimes corners are cut, and things go wrong. All the green grains are aligned with one of the edges of the unit-cell cube facing towards the tip of the screw.http://www.prosperitas.be/data/assets/cushman-core-harvester-parts-manual.xml All the green grains are aligned with one of the edges of the unit-cell cube facing towards the tip of the screw. This is indicative of the production process of the metal rods from which the screws are cut. The different purple colors in the head are caused by the stamp that shapes it and pushes the cross into the top of the screw. But that is where the similarities end. This difference in grain structure has consequences. When we zoom in on the shaft of the coarse-grained screw (Figure 5a), the large grains appear flattened in between the threads, and there is a strong change in grain size from the center to the edge of the shaft. In between the threads, some of these larger grains have even been forced apart to form cracks. This combination is bad news for the strength of the screw. When you tighten this screw, the force gets “focused” on the weak areas between the threads, and the screw breaks easily. In the fine-grained screw (Figure 5b), a minor grain size reduction is visible right at the edge of the shaft, but the internal structure is constant over the entire screw. This homogeneous structure distributes the force evenly over the screw, and it does not break easily. In the coarse-grained screw, long trails of carbide particles can be observed in between the grains, which effectively separate the grains and facilitate cracking. In the fine-grained screw, the grains show a lamellar martensitic microstructure with very few carbides. These microstructures exacerbate the difference in strength between the screws. So, I decided to cut up one of the failing screws and compare it with a screw from another box that had never given me trouble. Nothing crucial, you would think. But just imagine when this screw would have been used to hold up something a bit more impressive, like that big, heavy chandelier 10 meters above your head in the lobby of a hotel.https://www.interactivelearnings.com/forum/selenium-using-c/topic/16708/boss-br-1600-manual-pdf Then suddenly, the microstructure of a humble construction component, such as a screw, becomes crucial, and thinking about the crystallography and grain structure of everyday items turns out to be really important. This made me think about how important these little blocks are and how often they are not cared for properly. With that in mind, I thought it might be useful to pass on some little nuggets of information I have gathered over the years from many sources. Standard blocks can be purchased as a whole or personally made. No matter what, you need to know what you have. To do so, you should keep several copies of the following for every standard you have: This packet has optical, BSE, and SE images of the standard. This allows us to quickly find the standard we want while having all the information easily accessible in hand. This packet has optical, BSE, and SE images of the standard. This packet has optical, BSE, and SE images of the standard. This allows us to quickly find the standard we want while having all the information easily accessible in hand. You want to keep both a visual record of your standards, a record of what it is and the condition that it is in, to allow you to track any issues that may pop up (Figure 1). Therefore, having a note section is important. You may find that one of the areas of your standard gives anomalous values and should be avoided. You want to make sure this information is easily accessible to everyone that uses the standard. I suggest scanning and keeping electronic copies in a shared folder on your desktop. Most commercial standard blocks come pre-polished and carbon-coated. Over time, both of those will degrade and need to be redone. Usually, the carbon coating damages first, but you also need to check for burn marks and other beam damage done to the standard material itself. When repolishing and recoating, I usually do a solid 10 minute repolish with diamond paste.https://www.hotel-forsthaus.com/images/carrier-air-conditioning-service-manuals.pdf This removes enough material to eliminate the carbon coating and get new clean, undamaged surfaces while not change the physical appearance all that much. I try my best to avoid using an Al-based polishing material, as they tend to stick around too much and can interfere with my analysis on elements I use. With carbon-based polishing material, it is much easier to see the effects of the carbon. In the end, I do not tend to do quant work on carbon that much, while I often try to quantify aluminum. Whatever you do, document what was done. It can help you both head off and understand issues that may present. Your oils are bad for both the SEM cleanliness and the sample cleanliness. Avoid any sort of colloidal products with standards, as they do tend to flake with age. When not in use, samples should be held in a desiccator with good desiccant (Figure 3). You should try to keep it under vacuum for the best results. While taking this picture, I noticed I should dry my desiccant or replace it. I have seen some users keep a small plastic bag of fresh desiccant in the desiccator as a quick visual reference. You should try to keep it under vacuum for the best results.

While taking this picture, I noticed I should dry my desiccant or replace it. I have seen some users keep a small plastic bag of fresh desiccant in the desiccator as a quick visual reference. A good, well cared for standard will last multiple careers while giving consistent results time after time. Take the time to keep your standards in the best condition, and they will repay your time spent on them tenfold. As the sun began to rise over the frosty ground, the carnal wreckage was investigated, pondered over, poked and prodded, touched, and engaged in any other means of characterization at the disposal of the rag-tag cohort of farmers, engineers, enthusiasts, and politicians surrounding me. In hindsight, this scenario seems like something out of a science fiction novel or perhaps a post-apocalyptic memoir, but I can assure you that this is a common sight to behold. Common, at least, at the World Championship Punkin Chunkin. Although the beam failed in some of our early testing, it had previously been attached to a world-class, 7-ton, torsion catapult capable of launching pumpkins over a kilometer at nearly the speed of sound. It could withstand tensile loads exceeding the weight of a Boeing 747 and extended nearly 20 feet in length. All of that impressive performance was a thing of the past as I closely examined the jagged features at the fracture surface, the twists along the flanges of the I-beam, and the shards of carbon fiber shattered amongst the corn husks. I might have squinted my eyes and imagined some fatigue striations within the metal surface, but sadly this was the only means at my disposal of diagnosing the problem at the time. In a laboratory setting, I would have been able to not only characterize the elemental composition of the beam (it was a gift from a benevolent team sponsor) but also fully describe the crystalline structure with techniques like EBSD, XRD, and EDS. This type of material identification study is routine with modern analytical instruments, but recent advancements have taken this a step further. Had I known then what I know now, the unprecedented capabilities of high-resolution EBSD and ultra-high sensitivity of direct detection could have allowed me to understand and quantify, quite literally, the stressed state of the surrounding metal at the fracture surface. Sometimes these failures originate at some inclusion or material defect that could have previously been detected by methods like micro-XRF or EDS elemental analysis. Other times, inherent weaknesses in the system concentrate stress in ways that might not be apparent to the naked eye. Techniques like high-resolution EBSD and X-ray diffraction might be used to prevent these calamities. The list goes on and on. Although a researcher at semiconductor foundry might not be surrounded by farmers in the middle of a cornfield, they certainly may find themselves staring at an improperly functioning device, wondering where things went wrong. In this capacity and many others, I find myself relating to our customers. I empathize with their challenges, and I am excited to help them uncover solutions to some problems that they previously were not aware of. As EDAX employees, this makes us proud because we know that small things matter and our products and services help people discover scientific breakthroughs that make the world a better place. It reflects how little we know and how insignificant we are compared to the massive nature of the unknown. Science and human civilization still have a long way to go. We should remain respectful and humble about the world and nature. Furthermore, the impact on our perception of society and the world may have been changed forever. In my position as a Sales Manager, I promote and manage EDAX business and help our customers explore unknowns in small scale samples, hoping that it contributes to science. Airports, hotel breakfast, and complaints from my wife have become routine to me. Luckily, with “known” science and technology, the FaceTime and video calls do make it much easier for me to stay connected with my family while I’m traveling. I have been sitting still within my apartment, like most people around the world. Ironically, instead of using video calls to connect with my family, I am now using video conferences and other internet resources to conduct business remotely and keep in touch with our customers. I have become the family man that I never dreamed I would become over the past 10 years, and it is a dream come true. But when this is impossible, we realize the advantages of online meetings, including time, convenience, and economic impacts. In the scientific field, this is really valued by customers. Especially when a meeting is presented by an application scientist, rather than a salesperson. It can be depressing and frustrating, but at the same time, it is valuable and enjoyable to me that I could spend more time with family, something that I never did before, and I can make up for lost time with them. There is no escape from waking up in the middle of the night, changing diapers, and bottle feeding. Like it or not, that is all part of our life. The only difference is the last letter, which is “U” and “I”. It reflects my faith as well, there is always a bright side, and everything is at its best arrangement. Shawn was building an EBSD structure file for a new phase and encountered the following dialog for adding an atom to the unit cell. I realized I had implemented this capability several years ago for kinematical calculations of structure factors but had never really explored it’s impact on the calculations. I guessed that it would not have much of an impact, but I wasn’t entirely sure that was the case. The choice of ion type affects the atomic scattering factor used in structure factor calculations. I looked through our phase structure database for a binary compound containing Fe and decided to use a simple Al-Fe structure to check out the effect of the ion type selection on the structure factor calculation. I haven’t tried any other structures, so it is not a complete study, but I suspect other structures will follow the trend shown by the simple Al-Fe structure. Thus, my conclusion is, Don’t Sweat the Small Stuff. In the dialog above, it says the default Debye-Waller factor for iron is “0.003106 for bcc, 0.533 for fcc”. Does the choice of Debye-Waller factor matter. Here are dynamically simulated patterns for these values. To correctly use the new simulation tools, I need to expend some effort to learn more about Debye-Waller factors. Clearly, It’s the Little Things that Matter Most. Unlike standard-less analysis, the k-ratio is either calculated in the software or based on internal standards. For analysis with standards, it is measured from a reference sample with known composition under the same conditions as the unknown sample. As an applications engineer, sometimes users ask me where to order these standards. Usually, I point them to the vendors that manufacture and distribute reference standards where you can order either off-the-shelf or customized standard blocks. In addition to these commercial mounts, I always tell them that they can request a set of mineral, glass, and rare earth element phosphate standards from the National Museum of Natural History free of charge. These are very useful standards that I’ve seen widely used in not only the geoscience world but also in various manufacturing industries. These free standards are also great for those graduate students with limited budgets and ideal for practicing sample preparation (yes, I was one of them). You can find out more information about these standards and submit a request form by clicking on the link below: Yes, you read that right. These standards come in pill capsules containing from many tiny grains to a few larger ones and you need to mount them on your own (Figure 1). The first tricky thing is to get them out of the capsules. The grains in Figure 1 are almost the largest in this set and you won’t get too many of this size. Some of the grains are even too tiny to be seen at first glance. For the majority that are really tiny, you need to tap the capsule a couple of times to release the grains that get stick to the capsule wall, then you can open the capsule very carefully and let the grains slide out with a little tapping. I did this in a fancy way to make it look like a commercial mount (Figure 2). I ordered a 30 mm diameter circular retainer with 37 holes used by commercial mount manufacturers (Figure 3) and filled the holes with standards on my own. I must admit that the retainer is not cheap, but you can machine the mount by yourself or have a machine shop do it for you. In addition to looking pretty, the retainer ensures a good layout so you can quickly locate the standards you need during microanalysis, and you can mount the same type of standards on one block and get rid of the hassle of frequently venting and pumping the SEM chamber to switch standard blocks. When tapping the capsule to let the grains slide out and fall into the hole, the other holes were covered to prevent contamination (Figure 4b). These holes are small in diameter and pouring the epoxy mix directly will trap air bubbles in the hole to separate the grains from the epoxy mix. To overcome this problem, I filled up the hole by letting the epoxy mix drip down very slowly along the inner surface of the hole. But coarser grits can grind off tiny grains in this case, so I would recommend starting with a relatively fine grit based on the sizes of the grains you receive and always use a light microscope or magnifier to check the grinding. For polishing abrasive, I used 1 micron and 0.3 micron alumina suspensions on a polishing cloth. For the grains used as standards or quantification in general, the surface needs to be perfectly flat. However, the napped polishing cloth tends to abrade epoxy and the grains at different rates, creating surface relief and edge rounding, especially on tiny grains. To mitigate this effect, the polishing should be checked under a light microscope constantly and stopped as soon as the scratches are removed. A vibratory final polishing with colloidal silica is optional. Followed by ultrasonic cleaning and carbon coating, the standard mount is ready to use. A benefit of this approach is that the standards on the mount are changeable, so you can load all the standards you need on one mount before microanalysis. I used to make several individual mounted standards that can fit into the retainer (Figure 5b) but this process is very time consuming and much trickier to keep the small surface flat during grinding and polishing. With EDAX EDS software, in addition to quantification with these standards, you can also use them to create a library and explore the Spectrum Matching feature. The next time you want to quickly determine the specific type of a mineral, you can simply collect a quick spectrum and click the “Match” button, and the software will compare the unknowns to the library you just created. Testing detector speed or general software functionality is easiest on a simple material like an undeformed Ni or Fe alloy. But, I think it is a shame to perform longer duration tests on materials I have already seen many times before. For such occasions, I look through my collection of materials for something nice to map. This included large single-field scans and a Montage map, where we combine beam scans with stage movements for a large mosaic map. At the edge, the lighter areas represent the structure of the organism, while the darker areas are later sedimentary infill. In contrast, the infill is more equiaxed and shows topography due to compositional differences (Figure 1b). This wizard allows easy pre-imaging of the entire scan field to set the actual scan area. With the wizard, setting up such a large, 18 million point, 30-field Montage map over a 1.3 x 7 mm area can be done in a few minutes. But collecting data is not always that easy, especially if you are not sure what phase(s) you have in your sample. And ultimately, EBSD data collection is based on pattern analysis and then matching the detected bands against a lookup table. In most cases, you can just search the included EDAX structure file database that contains close to 500 phases and covers most commonly studied materials, such as the calcite used for the scans above. Partly, they are a result of our combined legacy. Over the years, we have seen many materials and often painstakingly identified which bands to select to get reliable indexing results. Nowadays, you can create phase files directly using atomic and crystallographic information. However, you can continue to extract the majority of “new” phase files from XRD databases, such as the AMCS, ICSD, or ICDD PDF databases. These databases contain 10’s to sometimes 100’s of thousands of phase descriptions that are based on XRD measurements. The XRD data shows which lattice planes are effective X-ray diffractors, and are also useful to construct a structure file for electron diffraction patterns. Often there are multiple possibilities for phases or minerals (e.g., solid solution series) available in the database. Which one to select. And in many cases, there is no single-phase file that matches the pattern exactly. There are always bands that do not get labeled or are shown in the overlay that are not visible in the real pattern. This is due to the differences between X-ray and electron diffraction intensities or simply incomplete database entries. Time for some human intervention. First, the color-coding itself. All bands are labeled with a color that corresponds to the IPF color triangle, so equivalent lattice planes get identical colors. This allows a visual inspection if bands that are designated with the same color also appear identical. When a pattern appears correctly indexed, but a number of bands are not labeled, the user can draw a line on the missing band. The software then shows which lattice plane corresponds to that band and also indicates all crystallographic equivalent planes. When it is still difficult to identify the correct indexing solution, it can be beneficial to bypass the Hough band detection and instead manually draw the bands for indexing. A good trick for low symmetry crystals is only to select the thinnest bands. These correspond to the lattice planes with the largest d-spacings and should be the important low-index crystallographic planes. By excluding the (often) large number of bands with similar bandwidths, you reduce the number of options and more quickly land at the best matching orientation or phase. When drawing a band, the software automatically shows where all the crystallographic equivalent planes should be. If a line is drawn where no band is present, you have the wrong candidate, and you need to look further. If all the indicated bands match in appearance and width, you can enable the reflector. This way, it is easy to interactively generate a matching phase file. Just keep in mind that when you have optimized a structure file to a pattern, it is a good idea to find some more patterns from that phase (if necessary, just rotate the sample to get a different orientation) and verify that all the bands in the other patterns are also properly identified. This is especially important for low symmetry materials where few lattice planes are equivalent. The initial reflector table (a) misses a number of strong bands. Manually selecting a band (b) shows which reflector this is and where the crystallographic equivalent bands should be. This can be repeated (c) until all clear bands have been labeled. The initial reflector table (a) misses a number of strong bands. Manually selecting a band (b) shows which reflector this is and where the crystallographic equivalent bands should be. The initial reflector table (a) misses a number of strong bands. Manually selecting a band (b) shows which reflector this is and where the crystallographic equivalent bands should be. This can be repeated (c) until all clear bands have been labeled. When you are working with a good pattern and successfully identify the phase and orientation, it is very tempting to keep looking for bands and completely fill the pattern with everything you can see. But that is often a bad idea, as the weaker bands will typically not get selected by the Hough transformation on the poorer patterns that are used during indexing. Enjoy playing with the materials and structure files, but don’t overdo it. Taking the concept away from delicious treats and moving towards something more technical, I’ve also enjoyed looking at the number of grains we need to measure with EBSD to get a good idea of the texture of a material. It’s the first commercial EBSD direct detector and will be launching soon. Traditionally, EBSD patterns are captured when the diffracted electrons strike a phosphor screen, where energy is converted into light photons, which are focused through a lens onto an imaging sensor, where the light photons are then converted back to electrons. However, a direct electron detector is just that, it captures the diffracted electrons directly. This allows us to count the electrons in an EBSD pattern directly. This is because the actual live EBSD pattern does not have a uniform intensity across the sensor, as shown in Figure 2. In this example, a background collected while imaging many grains was collected and subtracted from the live signal to produce the image in Figure 1. The background image has the spatial information for a specific orientation removed, while retaining the overall intensity gradient that is a function of the material of interest and the sample geometry. The cross-hair image visible in Figure 2 shows the location of the seams between the detectors. These can be masked out of the image if desired but are quickly minimized with this background correction. After background subtraction, I drew a line across the image, and the intensity profile across this line is shown in Figure 3. This profile shows that the final processed EBSD pattern has a dynamic range of about 1,700 electrons. I could decrease the exposure time, decrease the beam current, or do both. In this case, I continually decreased the exposure time to find where the EBSD pattern indexing started to fail. Figure 4 shows an EBSD pattern where the maximum number of electrons is 20 and the average number of electrons is 10. Talk about doing a lot with a little. This performance is enabled by the single electron sensitivity and zero readout noise of the detector, which makes this camera very exciting for low beam dose applications for beam-sensitive materials. I look forward to sharing more later. Sometimes, it requires additional education to help users understand a concept. Other times, it requires an exchange of numerous emails. At the end of the day, our goal is not just to help you, but to ensure you get the right information in a timely manner. Why? There is so much information hidden in the spectrum that we can quickly point out any possible issues. With a single spectrum, we can quickly see if something was charging, tilted, or shadowed (Figure 1). We can even see weird things like beam deceleration caused by a certain imaging mode (Figure 2). With most of these kinds of issues, it is common to run into major quant related problems. Any quant problems should always start with a spectrum.
