Powder Bed Fusion (PBF) is an additive manufacturing (AM) process capable of producing metal parts with a wide variety of complex and intricate components. AM parts are often treated as uniform bulk materials, however, our initial results on AlSi10Mg suggest that AM parts may in some ways resemble a composite material where different microstructural regions- corresponding to the melt pool boundaries in laser AM parts- each have unique local mechanical properties. We perform in-situ SEM microtensile experiments to measure ductility and tensile strength for AlSi10Mg samples. Microstructural differences of melt pools are correlated to tradeoffs in mechanical properties and deformation mechanisms.
