| Abstract | In the present work, a CuCrZr alloy characterized by ultrafine grains and nanoscale particles was prepared by equal-channel angular pressing (ECAP) at 450 degrees C. A desired combination of a tensile strength (580 MPa) and an electrical conductivity (81% International Annealed Copper Standard) is simultaneously obtained in the as-ECAP-processed CuCrZr alloy without additional aging treatment. The improved properties can be mainly attributed to the ultrafine grains and nanoscale precipitates. This processing may pave a way to develop the CuCrZr alloys having high strength and high electrical conductivity for engineering applications. |
