r0005">We investigated the effect of cryo-rolling process to Cu and CuCrZr alloy by tensile test and EBSD.
r0010">Cryo-rolling process simaltaneously increased strength and ductility of Cu as previously reported.
r0015">Cryo-rolling process increased strength of CuCrZr alloy without loss-of-ductility compared with conventional cold-rolling process.
r0020">We observed heterogeneous grain size distribution in cryo-rolled Cu but not in cryo-rolled CuCrZr alloy.
r0025">We found temperature-transition of texture formation in the rolled CuCrZr alloy.
