Combining severe plastic deformation and precipitation to enhance mechanical strength and electrical conductivity of Cu–0.65Cr–0.08Zr alloy

Journal of Materials Research and Technology, 2020
Cu–0.65%Cr–0.08%Zr alloys display a superior combination of mechanical and electrical properties than pure copper. This is due to the solid solution hardening solubility of Zr and Cr as low content alloying elements in copper.
