TKD 101: An Introduction to Transmission Kikuchi Diffraction

Webinar presented by Dr. Chad Parish, Research and Development Staff Member in the Radiation Effects and Microstructural Analysis Group, Materials Science and Technology Division, Oak Ridge National Laboratory, and recorded as part of the Microanalysis Society (https://the-mas.org/) webinar series on December 04, 2020. It consists of a 50-minute presentation, followed by a Q&A. Description: Over the last two to three decades, electron backscatter diffraction (EBSD) emerged as one of the most powerful and exciting methods in electron microscopy to quantify the crystallographic microstructures of materials. Over the last decade or so, transmission Kikuchi diffraction (TKD) has emerged as a vital and important complement to EBSD. This seminar will (1) briefly discuss the basics of TKD and put them into their historical perspective compared to EBSD; (2) discuss how to acquire TKD data, with emphasis on artifacts, errors, and things to watch out for; and (3) show a few examples of practical materials problem solving using TKD. Keywords: SEM, TKD, EBSD
