Abstract

X-ray diffraction is a well developed and mature experimental technique that has been used to investigate the micro structure of materials for decades.  However, it does have some long standing limitations, such as its difficulty to analyse individual grains within a multi-grain (bulk) sample.  Enter in Three Dimensional X-ray Diffraction (3DXRD), a cutting edge technique that has the ability to access information on the structure of materials that previous techniques could not reach.  With 3DXRD, each individual aluminium grain can be investigated simultaneously, allowing new insight into phenomenon like defect nucleation and grain growth.  In this seminar, I will go over the main concepts of 3DXRD as well as my role in developing this technique, particularity the development of the Quad Near Field X-ray Detector.

The talk is from 3-4 pm (snacks at 2:30!). Make sure to follow the Graduate Seminar Series on Facebook.
