Development of bulk thermoelectric N-type SiGe alloy by laser powder bed fusion

Résumé

Like printing in its day, additive manufacturing has revolutionized current production methods in many areas like aeronautics, military or medicine. Among these methods, Laser Powder Bed Fusion (L-PBF) is prevalent to printing complex metal parts in small and medium series. Techniques developed recently in L-PBF pave the way for producing new types of materials via this method, including thermoelectric (TE) materials. This document presents the research work carried out at CEA to study the manufacturing of silicon-germanium alloy by L-PBF, a TE material intended for high temperature applications. In this study, we achieved successfully the printing of several dense samples, and then discuss their microstructures, chemical composition and thermoelectric properties.
