Research on Cu-Cr Alloy Produced by Equal Channel Angular Pressing

Abstract:

Cu-7.5wt%Cr alloy was subjected to severe plastic deformation at room temperature using the procedure of equal channel angular pressing. Microstructures of the processed material were investigated by metallographic analysis, SEM and TEM. The results show that grains size of the processed materials was obviously fined. Cr precipitated in matrix was distributed uniformly. And micro-hardness of the copper alloy increased a lot.
