Summary
In this joint EDAX-Cameca webinar the use of chemical information collected together with EBSD microstructural data is reviewed. Combined analysis may be performed from the cm- to nm- scale in the scanning electron microscope. The availability of simultaneously collected EDS data ensures successful EBSD analysis of multiphase materials and identification of particles.
For even higher resolution data, EBSD may be paired with atom probe tomography. There it can both be used to pinpoint the exact volume of material to be analysed with atom probe tomography and also to provide the microstructural framework to interpret APT data once it is collected.
Speakers
René has been working as applications specialist for EBSD and later also EDS at the EDAX European support office in Tilburg, The Netherlands since 2001. His focus is on instrument demonstrations, conference and workshop presentations, and after-sales customer support. This includes (on-site) training courses, assistance with analytical problems, and scientific collaborations. Although focused on Europe, his work has brought him to customers and conferences all over the world. This international travel is a great bonus for his hobby geocaching, where he tries logging at least one cache in every city visited.
As he has always been fascinated by the physical world around him, René has chosen to study geology at Utrecht University with specialization in materials science from a geological perspective. René’s first introduction to electron microscopy and microanalysis came during his undergraduate thesis on deformation and pressure indicators in natural fault rocks from New Zealand, which involved a significant amount of SEM and TEM work. Later during his PhD thesis on nanometer-scale melt structures in upper mantle rocks, he also learned about high resolution TEM imaging and EDS analysis. Around this time, he also started using EBSD on a system without any automation.
Rene’s background in geology gives him a slightly different view on materials research, which has proven invaluable over the years at EDAX. In geology, one must often look at a material without any prior knowledge on how it was formed. Applying this view to man-made materials can be a great help in explaining unexpected test results or materials failures that customers need to understand.
Katie joined Cameca Instruments in Madison, WI in August 2014 as an Applications Scientist. Katie received her Bachelor of Science in Chemical Engineering from the University of Maine in Orono, ME; and a Ph.D. in Chemical Engineering from the University of Colorado-Boulder specializing in nanoparticle synthesis. The title of her dissertation was “Shape Control and Oxidation Behavior in Colloidal Nanocrystals”, which focused on the synthesis of new types of nanoparticles and even figuring out how to synthesize fun shapes of nanoparticles. After graduate school, Katie transitioned into the field of transmission EBSD at the National Institute of Standards and Technology in Boulder, CO.
At Cameca, she prepares and runs customer samples as well as developing new applications for atom probe tomography. Over the last few months, Cameca and EDAX have been collaborating closely in employing transmission EBSD to atom probe tomography samples to identify grain boundaries. It’s been a great collaboration so far and we look forward to working together in the future. In her spare time, Katie enjoys tap dancing and one of her goals is to get a good EBSD map of her taps which she guesses are primarily aluminum these days.
