摘　　要：本文以耐蚀合金Alloy59丝材为研究对象,通过力学性能测试、金相显微镜和扫描电镜分析等方法,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Alloy59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,晶粒从变形晶粒转变为等轴晶。Ni-based superalloy Alloy59 wire was studied in this paper.The microstructure and properties of Alloy59 wire subjected to different solution treatments were researched through the mechanical properties testing,metallographic microscope and scanning electron microscope analysis.The results show that the solid solution temperature significantly affect the microstructure and mechanical properties of Alloy59.With the increase of heat treatment temperature,the tensile strength decreased,the plastic deformation of grains increased significantly,from the deformed grain into equiaxed grains.
