 So we are going to show you the real time EBSD analysis which is available in IIT Kanpur at the Department of Material Science Engineering. This is a microscope which is can do all kinds of EBSD analysis. The sample is loaded inside this chamber and this is the EBSD camera which goes inside whenever we are required to detect the EBSD analysis and after we load the sample, sample is basically loaded this kind of holders where you can see there is automatic tilt. So you do not need to tilt it, nowadays this kind of holder is available. So sample will remain tilted in this position at about 65 to 75 degrees and then if I show you what is there inside, you can see this is the sample holder and the sample is mounted here which is automatically tilted with respect to the horizontal by 65 to 75 degrees and this is the phosphor screen and the camera which goes inside and this is the through which the electron falls on the sample and there are other detectors which is attached to any ACM or scanning electron microscope. Now we will just simply go back to the original position that is the sample, so this is the basket image obtained when the sample is tilted. Now once it is there on the computer, we can actually take any point on the sample and get a EBSD pattern, so I will explain you how it is done. So now if we import this image on the computer screen there, so as you see the same image is imported there, now if we click just the button just mouse here, we can immediately get the EBSD pattern on the computer screen, this is what is the automation nowadays possible to get. So this is the unprocessed EBSD pattern which is which contain lot of noise and that needs to be corrected, it is getting the EBSD pattern actually normally 16 EBSD patterns are collected from one position and they are integrated over the time scale, so the quality of the pattern can be improved and then the background subtraction is done to remove the background noise, it is now collecting the EBSD patterns from that particular point which is selected on the secondary electron image on the sorry on the backstreet electron image and then it is collecting the EBSD patterns. Well so we would like to show you how this is done online in a fully automated system, so as you see on the left side of this computer screen there is an electron microgap which is basically a basket electron microgap taken when the sample was tilted to 65 to 75 degrees and then as I click you will see that a pattern will appear on the right side, so if I click it here, so a pattern appears on the screen and you can see the pattern is even indexed, so this is the quality of the EBSD pattern one can get nowadays using this kind of high quality detectors and by knowing this the typical crystal structure of the material we can actually see that even this is the orientation of the crystal with respect to the sample, so from the laboratory frames we can get actually what is the exact orientation of the crystal, so if I collect the information from different grains of the material in the for which we are doing the study we can actually get all the information from each grain and then store it into the computer and finally it is possible in fact to show that how the gain this information can be processed and again map can be obtained which I will show you in a nutshell, so suppose this is a this is an austenitic stainless steel sample which is a FCC crystal structure and this is the grain different grains in the crystal and once we go down and once you take the information from different grains which are present in the sample after collecting the EBSD patterns and we can just process in the software and then we can plot it in terms of the gain orientations and this is the way again orientations are shown by different colors this each color indicate the orientation of the grain as you see the 01 actually is depicted in red color whether 01 is depicted in green and 111 is depicted in blue, so therefore any grain which is looks like a red is basically close to 01 orientation whether one grain like this one or this one which can be inferred that they are oriented along 01 or 01 orientations on the other hand there are grains like this which is blue they are oriented along 111, so therefore in a large number of grains we can collect the orientation information from all the grains or rather each of these grains and then we can figure out even what is the kind of orientations here the fraction number of grains and this is the fraction and this is the number of neighboring grains and we can find out the orientations by doing certain analysis and that is what is done in this picture here the pole figures corresponding to 100, 110 and 111 are shown and as you can see it is the rest is visibly there is some texture present in the sample and this texture is not so clear from this pictures but in the class I will discuss you each of these cases and I will show you that we can get information and get the texture type or a particular material form such a kind of analysis. In fact one can plot one can make a plot in mass pole figure for like this in which one can show the cluster of the grains with orientations like 001, 101 or 111 and by knowing this orientations or the number of clusters present at each orientation one can get which is the predominant texture as you see here the most of the grains are oriented along 101, so there are large number of green regions close to the 101 on the other there are very few blue region close to 111, so therefore very few grains are there which are oriented along 111 and that is obvious because in a normal material externally steel the grain oriented should be predominantly either 001 or 101 type and so therefore one can actually get such a kind of lots of kind of information from one single run of EBSD and this is what makes this technique so useful in the real situations where we need to analyze the line number of grains and get information regarding their orientations with respect to the laboratory frame of frame and also the whether these orientations are freedom random or they are preferred that is whether there is any texture present or not this all can be inferred from such a kind of analysis such a facility is existing almost every lab almost many labs in India and one can prepare a sample and then just put it inside a microscope and obtain such patterns in a 6 to 8 hours time and then process this information in a software which are available in the market and then infer lot of information.
