Aging behavior and precipitates analysis of the Cu–Cr–Zr–Ce alloy

Microstructure of the Cu–Cr–Zr–Ce alloy was investigated by high resolution transmission electron microscopy (HRTEM), along with micro-hardness and electrical conductivity measurements. The alloy hardness and electrical conductivity can reach 170 HV and 66% IACS, respectively, after 80% cold rolling and aging for 16 h at 300 °C. Under the same aging conditions, without cold rolling, the hardness is 90 HV and electrical conductivity is 44% IACS....
