Abstract:Copper alloy is widely used in electric power,mechanical manufacturing,chemicalindustry,automobile, electrical instruments and construction industries because of its good ductility,wear resistance,thermal conductivity and high conductivity. However,there are some problems in the Gleeble thermal mechanical simulation experiment during theres earch of new copper alloy materials,such as the difficulty of thermocouple welding,unstable heating and determination of isothermal zone,which leads to the high failure rate of the experiment,the inaccurate data,and the difficulty of analysis and so on. In this paper,the thermal-mechanical simulation experiment of Cu-Cr-Zr alloy has been studied systematically with Gleeble3800 system. Through a variety of means to solve the above problems,the success rate of the experiment reached more than 90%,greatly improved the efficiency of the experiment.The results of tensile test of Cu-Cr-Z ralloy show that the whole sample deforms at high temperature,but the main deformation zone is in the uniform temperature region of the middle 6 mm region. The deformation of the middle 6 mm isothermal zone is about 90%-110%.
