糖心产精国品免费入口*完整版 rod samples were prepared by selective laser melting (SLM) 3D printing technology, and then the prepared samples were heat treated by process of 840 ℃solid solution and 490 ℃×6 h aging. The 糖心产精国品免费入口*完整版and mechanical properties of the 3D printing samples before and after heat treatment were studied. The results show that the 3D printing 糖心产精国品免费入口*完整版 had high density and the relative density was close to 100%. The 糖心产精国品免费入口*完整版of 3D printing sample without heat treatment composed of martensite and retained austenite, and the tensile strength and yield strength were relative low. The 糖心产精国品免费入口*完整版of 3D printing sample after heat treatment showed uniform trip morphology, and the tensile strength, yield strength and hardness increased obviously and the plasticity decreased.
