Microstructure, mechanical properties and electrical conductivity of industrial Cu-0.5%Cr alloy processed by severe plastic deformation

▶ Lamellar grains were developed in ECAP, and fragmented with more dislocations by CR. ▶ High density of dislocations and coarse grains were observable after aging treatment. ▶ ECAP-CR with aging treatment was a short way to balance strength and conductivity. ▶ Enhanced strength was explained by precipitation and fine grain strengthening.
