Abstract

The porous 17-4PH stainless steel was prepared by selective laser melting (SLM), and its microstructure and mechanical properties were studied. The results showed that the structure of the SLM-formed sample contains a considerable amount of martensite and a small amount of austenite. After heat treatment at 1040 °C × 2 h(Air Cool, AC) + 480 °C × 4 h(AC), the 17-4PH stainless steel formed by SLM was transformed into a recrystallization structure, with a more uniform microstructure and refined inner martensite. The martensite in the alloy was refined. The cross-sectional hardness of the sample was increased by 142%, and the longitudinal section was increased by 51.7%. During the compression process of the porous 17-4PH stainless steel, the first stage was elastic deformation; there was a linear relationship between the stress and the strain. The second stage was the plateau stage (yield stage), and there was a long deformation plateau, which indicated that the porous 17-4PH alloy had good ductility and strong energy absorption capacity. The third stage was the densification stage, with the increase in strain, the pillars of the porous stainless-steel alloy were completely bent, the layers touched each other, and the compressive stress rapidly increased. After heat treatment, the martensite was refined, and the M7C3, ε-Cu, and NbC were precipitated; the yield strength and the elastic modulus of the porous 17-4PH stainless steel increased by 21% and 35%, respectively.
