Additive Manufacturing of metal alloys: Why XRD is an important tool for characterizing metal powders and built components

Live Webinar November 19th, 2020

For metal fabrication processes such as casting, forging, and isostatic pressing, the heating-cooling regimes are more prolonged, controlled, and homogenous. However, for powder bed additive manufacturing (AM) processes such as SLM, EBM, and DED, the heating-cooling regimes are very fast and location-specific, which can lead to different microstructures than those obtained with conventional processes, even with the same alloy composition, and these can change further with post-treatments such as heating, machining and isostatic pressing.

X-ray diffraction (XRD) is a non-destructive analytical technique that can be used to study these processes by measuring microstructural characteristics such as phase composition, crystallite size, texture (crystallite orientation), and residual stress/strain.

In this webinar, Dr. Scott Speakman will discuss the importance of XRD for metal additive manufacturing, including powder and component analysis, with several application examples presented.
