摘要: 为了改进50Cr-50Ni镍基合金性能,提高其应用范围,进行了1180 ℃不同时间的固溶处理试验,并对其显微组织形貌、力学性能和耐蚀性能进行了测试与分析。结果表明,50Cr-50Ni合金在1180 ℃固溶2 h时的组织均匀性较好,伸长率和耐蚀性较好。随着固溶时间的延长,其伸长率和耐蚀性变差,但抗拉强度和硬度提高显著。

Abstract: In order to improve the properties of 50Cr-50Ni alloy and expand its application range, the solution treatment test at 1180 ℃ for different time was carried out, and its microstructure, mechanical properties and corrosion resistance were tested and analyzed. The results show that the 50Cr-50Ni alloy has better microstructure uniformity, elongation and corrosion resistance when solution treated at 1180 ℃ for 2 h. With the extension of solution treatment time, its elongation and corrosion resistance deteriorate, but the tensile strength and hardness increase significantly.

Key words: 50Cr-50Ni alloy, solution treatment, microstructure, properties
