In the present work,a CuCrZr alloy characterized by ultrafine grains and nanoscale particles was prepared by equalchannel angular pressing (ECAP) at 450 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.
