激光增材制造316L不锈钢微观组织与缺陷控制研究

Research on microstructure and defect control of laser additive manufacturing of 316L stainless steel

实习内容：

激光定向能沉积（DED）技术在制造大尺寸形状复杂不锈钢构件上具有较好的应用前景。但是DED过程中复杂热循环容易引起不锈钢组织不均匀，导致力学性能各向异性和耐蚀性能恶化。本项目将开展DED增材制造316L的工艺研究，分析成型参数、热处理工艺对材料微观组织演变和力学性能的影响，为复杂316L构件制造和修复提供工艺参考。

Laser directed energy deposition (DED) technology has a good application prospect in the manufacture of large-size and complex shaped stainless steel components. However, the complex thermal cycle in the DED process can easily cause uneven structure of stainless steel, resulting in the deterioration of mechanical properties anisotropy and corrosion resistance. This project will carry out the process research of DED additive manufacturing 316L, analyze the influence of molding parameters and heat treatment process on the microstructure evolution and mechanical properties of materials, and provide process reference for the manufacturing and repair of complex 316L components.
