Abstract

The hardness, compressive yield strength and electrical conductivity of CuCrNiAl alloy before and after 4 GPa pressure treatment were measured, and the microstructure of the CuCrNiAl alloy before and after 4 GPa pressure treatment were analyzed by metallurgical microscope, transmission electron microscopy and scanning electron microscope. Based on the experimental results, the effects of 4 GPa pressure heat treatment on the mechanical properties and electrical conductivity of CuCrNiAl alloy were discussed. The results showed that 4 GPa pressure treatment can increase the hardness and compressive yield strength of the CuCrNiAl alloy, and reduce its electrical conductivity. After 4 GPa pressure treatment and aged at 500°C for 1 h, higher mechanical properties and electrical conductivity of CuCrNiAl alloy could be obtained.
