摘      要：Laser powder bed fusion(LPBF)is the most widely used metal additive manufacturing *** is a novel layer-by-layer manufacturing technique based on a geometrical model that provides a suitable alternative for material *** mode is widely used in laser and electron beam ***(Ni)alloy prepa-ration using the LPBF method has attracted considerable attention in several areas,owing to the high corro-sion resistance and good mechanical properties of the prepared *** specific conditions of solidification through the metal fused during the selective laser fusion process and its layer deposition induces microstruc-tural peculiarities,including the formation of a supersaturated solid solution,extreme microstructural refine-ment,and the generation of residual ***,heat treatment and hot isostatic pressing,which are generally applied to conventionally manufactured Ni alloys,may need to be altered to adapt to the met-allurgical properties of Ni alloys manufactured using direct metal laser deposition and address particular is-sues resulting from the process *** studies have been conducted on this topic over the past few years,suggesting different approaches for addressing different alloying *** review summarizes the latest scientific findings in the area of thermal treatment for selective laser sintering of additively manufactured Ni alloys.
