激光快速成形Inconel 718拉伸性能和ANSYS模拟分析研究

采用激光快速成形技术制成Inconel718材料，对其拉伸性能和微观组织进行分析。结果表明，其拉伸性能和微观组织均具有各向异性。采用ANSYS分析软件得出试样拉伸应力分布图，通过模拟数据与试验数据对比，两者应力-应变曲线得到很好吻合，为Inconel718材料复杂机械构件在研制阶段通过有限元分析提供设计依据。

Reseaech on Tensile Properties and ANSYS Simulation Analysis of Inconel 718 by Laser Rapid Forming Process

Inconel 718 was made by laser rapid forming technology. The tensile properties and microstructures were analyzed. It is showed that the tensile properties and microstructures are anisotropy. The specimen tensile-stress distribution was obtained by simulation software ANSYS. By comparing the simulation data with the experimental data, both the stress-strain curves in good agreement, it is provide the design basis for the complex mechanical components of Inconel 718 material in the development stage through ifnite element analysis.
