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.
