摘　　要：要本文以GH4145合金丝材为研究对象,通过力学性能测试、金相显微镜和扫描电镜分析等方法,开展了冷加工工艺对合金丝材的显微组织和力学性能的研究。结果表明:生产过程中,走丝速度对抗拉强度影响不大;相同变形量的GH4145合金丝材强度增加比例接近,可根据固溶后强度选取合适的变形量。Ni-based superalloy GH4145 wire was studied in this paper.The microstructure and properties of GH4145 wire subjected to cold deformation were researched through the mechanical properties testing,metallographic microscope and scanning electron microscope analysis.The results show that heat treatment holding time has little effect on tensile strength;the increase ratio of the strength is similar when the deformation of wire is the same,suitable deformation can be designed according to the strength after solution.
