Abstract

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
