摘要：
This study examines the effects of various heat treatments on the mechanical properties and corrosion resistance of Inconel 625 alloy produced via laser wire melting. The as-deposited alloy exhibits residual stresses due to multiple thermal cycles, characterized by columnar dendrites with sub-crystalline segregation. Stress relief treatment at 750 degrees C enhances strength through diffusion strengthening and stress relief, while treatment at 1150 degrees C improves elongation by transforming dendrites and removing subgrain structures. Both treatments slightly and substantially enhance corrosion resistance, respectively, highlighting the importance of developing effective heat treatment strategies for additive manufacturing components.
