Deformation Behavior and Processing Parameters of Cu-3Ag-0.6Zr Alloy during Compression at Elevated Temperatures
School of energy, power and mechanical engineering, North China Electric Power University, Beijing 102206, PR China
Hot compression tests of the Cu–3Ag–0.6Zr (wt.%) alloy were carried out on a Gleeble-3800 testing machine at various strain rates and at different deformation temperatures. The stress–strain behavior of the alloy during the deformation process are analyzed. The results show that the hot deformation behavior of the Cu–3Ag–0.6Zr alloy is markedly affected by the interaction between the work hardening and the dynamic recrystallization at different strain rates and temperatures. The thermal deformation activation energy is calculated as 248.8384 kJ mol−1 and the hot compression constitutive equation has been established. The processing map of the alloy has also been established. According to the obtained processing map, the preferable domains for hot working are identified at a strain rate of 10-3 s-1 and at 900–940 K or temperatures higher than 1023 K.
