The work hardening curve of Cu-Ag alloy is drawn after applying cold deformation. The tensile strength, elongation and microstructure of alloy are respectively tested and observed after annealing. The results show that the alloy shows obvious work hardening effect after cold deformation. The strength of the alloy is increased firstly and then keeps constant as working rate increases. However, the elongation and electrical conductivity exhibit opposite change rule. In addition, the larger the working rate is, the less the recrystallization temperature is. When the deformation is more than 60%, the recrystallization temperature tends to stable (300~400 ℃). ©, 2015, Journal Office of Special Casting and Nonferrous Alloys. All right reserved. Source
