摘要
采用轧制复合法制备了新型铜/锰白铜/铜弹性材料,通过显微组织观察、电导率和弹性模量测试等研究了退火温度对材料显微组织及性能的影响。结果表明:通过制定合理的轧制工艺可制备厚度为0.2 mm的铜/锰白铜/铜弹性材料,芯材与铜层形成了良好的结合;不同温度下退火处理2 h后发现,铜/锰白铜/铜弹性材料的电导率随退火温度的升高而先升高后降低,400℃回火后的电导率最高,为4.23×10~7(Ω·m)^(-1);退火处理对该材料的弹性模量影响不大。
A new Cu/BMn40-1.5/Cu elastic material was prepared by rolling compound method.The effect of the annealing temperature on microstructure and properties of the material was studied by microstructure observation,electric conductivity test and elastic modulus test.The results show that the Cu/BMn40-1.5/Cu elastic material with thickness of 0.2 mm could be prepared by taking proper rolling process.The bonding between the core material and the copper layer was good.After annealing for 2 h at different temperatures the electric conductivity of the Cu/BMn40-1.5/Cu elastic material increased first,that a peak value of 4.23×10~7Ω^（-1）·m^（-1）could be obtained when the annealing temperature was 400℃,and then decreased with the increase of annealing temperature. Annealing process had little effect on the elastic modulus of the elastic material.
