The microstructural and mechanical properties of Inconel 718 were determined on the
specimens manufactured by selective laser melting (SLM) of prealloyed powder. High-
density (99.8%) cylindrical specimens were built with four orientations (0°, 45°, 45°× 45° and
90°) in relation to the building and scanning directions. Because of directional, dendritic-
cellular grain growth, microstructure of the as-built specimens was characterized by
columnar grains of supersaturated solid solution with internal microsegregation of Nb and …

Effect of solution heat treatment on microstructure and mechanical properties of laser powder bed fusion produced cobalt-28chromium-6molybdenum
Abstract Cobalt-chromium-molybdenum (CoCrMo) alloys have excellent properties that
make them widely used in dental applications. Selective laser melting (SLM) is a laser
powder bed fusion (L-PBF) additive manufacturing (AM), or 3D printing, technique that can
fabricate functional parts directly using these alloys. In this work, SLM is used to fabricate
CoCrMo samples and they underwent different heat treatments originally designed for
casted CoCrMo alloy. The mechanical properties, such as ultimate tensile strength, yield …
