Abstract

Abstract: Selective laser melting forming technology is a promising method for manufacturing hard-to-machine metals such as TC4 alloy. The difficulty of the microstructure control is its bottleneck restricting in large-scale application. Research progresses on the effects of selective laser melting process parameters are summarized on the microstructure, residual stress distribution and microstructure change of TC4 alloy after heat treatment, and the microstructure-related future research directions are prospected.

Key words: selective laser melting, TC4 alloy, heat treatment, residual stress, martensite
