This study provides a summary of the effect of heat and hot isostatic pressing treatments on the microstructure and mechanical properties of IN625 alloy processed by selective laser melting. IN625 metallographic and tensile testing specimens were additively manufactured in four different orientations and then subjected to stress relief, low solution annealing and hot isostatic pressing treatments. The as-built alloy exhibited the highest tensile strength, the lowest ductility and the highest anisotropy of mechanical properties among all the tested specimens. Heat and hot isostatic pressing treatments provided an improvement in ductility and homogeneity, but at the expense of lower strength characteristics. The results of this study provide some indications for improving the mechanical properties of additively manufactured IN625 alloy components.

Abstract Additive manufacturing has recently expanded its potential with the development of selective laser melting (SLM) of metallic powders. This study investigates the relation between the mechanical properties and the microstructure of Ti6Al4V alloy produced by SLM followed by a hot isostatic pressing (HIP) treatment. HIP treatment minimizes the detrimental influence of material defects. Tensile specimens produced with reference to specific building axes were prepared using a Renishaw A250 system. It has been found that the tensile strength and elongation depend on specimen building direction. Microstructural and textural characterizations were carried out to identify the source of differences.
