摘要：In this paper the effects of thermal-mechanical treatment on microstructure and properties of Cu-Zn-Fe alloy have been studied by metallographic observation, SEM, hardness measurement and electrical conductivity measurement. The mechanical properties and electrical properties of Cu-Zn-Fe alloy are improved through hot rolling, cold rolling, annealing at high temperature, further cold rolling and annealing at low temperature. The optimum final annealing temperature is 200°C, and the optimum annealing time is 2 hours. The best comprehensive properties of the alloy can be reached at hardness of 194.83HV and conductivity of 37.2% IACS. Fe works as solute atoms in the alloy, and Fe can inhibit the growth of the grain during the process of deformation and heat treatment, thus improving the mechanical properties of the alloy. No precipitation strengthening phenomenon was observed during the process of annealing at 480 °C, which indicates the alloy is a working hardening alloy.
