Study on Aging Characteristic of Cu-Cr-Zr-Ce Alloy
The effect of aging parameter and deformation on the property of Cu-0.35Cr-0.038Zr-0.055Ce alloy after aging was studied. The result shows that, after solution at 920℃ for 1h ,the alloy can obtain higher electrical conductivity and microhardness aged at 500℃ for 2h. The process of precipitation of the secondary phase can be accelerated with cold deformation before aging, Upon aging at 500℃ for 0.5h after 60% cold deformation, the values of electrical conductivity and microhardness are 69.0%IACS and 152.8 HV respectively, but they are only 56.3%IACS and 130HV upon directly aging after solution. With the addition of a trace of rare earth element Ce, the value of microhardness of Cu-0.35Cr-0.038Zr alloy increases 18~25 HV,while the value of electrical conductivity drops a little.
