Check for microstructural defects in additive manufacturing

Live webinar 27 April 2022

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. Olga Narygina will discuss the importance of XRD for metal additive manufacturing, including powder and component analysis. She will present several application examples using Malvern Panalytical high resolution Empyrean series III X-ray diffractometer, the gold standard for those in research.
