摘　　要：本文以铁镍基高温合金HGH1140丝材为研究对象,通过力学性能测试和金相显微镜等分析方法,开展了不同温度固溶处理后合金丝材的显微组织和力学性能的研究。结果表明:固溶温度显著影响HGH1140合金力学性能和组织状态,随着热处理温度的升高,合金的强度明显下降,塑性明显上升,晶粒长大。FeNi-based superalloy HGH1140 wire was studied in this paper.The microstructure and properties of HGH1140 wire subjected to different solution treatments were researched through the mechanical properties testing and metallographic microscope analysis.The results show that the solid solution temperature significantly affect the microstructure and mechanical properties of HGH1140 alloy.With the increase of heat treatment temperature,the tensile strength decreased,the plastic deformation of grains increased significantly,and the grains grow.
