In this webinar, Professors Hebert, Rainer and Dr Sun (from University of Connecticut) and Dr Lemmens (Thermo Fisher Scientific), will present the application of various EM characterization solutions on two different use cases. First, they will demonstrate how state of the art scanning electron microscopy can be used to characterize Ti-6Al-4V powders. Recycling these powders plays an important role in the AM production process and they will show how electron microscopy, using EDS mapping, helped identifying mechanisms of oxygen increase in those powders with recycling.

Furthermore, they will show how a wide range of defects that develop in 17-4 PH stainless steels during the AM process can be examined in more detail, using focused-ion beam milling, electron back-scattered diffraction (EBSD) and transmission electron microscopy. In particular, they highlight the evolution of inclusions in the additively manufactured components and the potential sources for those inclusions in the starting powders, ultimately proving that the use of state-of-the-art electron microscopes is indispensable for developing a better understanding of additive manufacturing microstructures and defects.

By attending this webinar, you will:

  • Learn how to apply electron microscopy for characterization of microstructures in additive manufacturing
  • Obtain insight into powder characteristics with electron microscopy
  • See how heat-treatment affects microstructures of additively manufactured stainless steels
  • Learn how multi-scale characterization approaches can be applied to a wide range of additively manufactured samples
