摘　　要：采用固溶+冷变形(80%变形量)+不同温度和时间时效工艺制备了Cu-0.33Cr-0.06Zr合金试样,研究了时效温度以及时效时间对Cu-0.33Cr-0.06Zr合金导电率和显微硬度的影响。结果表明,固溶后冷变形加时效可以显著提高合金的导电率和显微硬度。固溶和冷变形后Cu-0.33Cr-0.06Zr合金的合理时效工艺为450℃下时效2 h,经此工艺处理后合金的导电率可以达到83%IACS,硬度达到195 HV0.1。Cu-0.33Cr-0.06Zr alloy was prepared and solid solution treated, and then cold deformed by 80% stain and aged at different temperatures and time.The effects of aging temperature and aging time on conductivity and microhardness of Cu-0.33Cr-0.06Zr alloy were investigated.The results show that the conductivity and microhardness of the alloy are effectively improved by aging process after cold deformation.The proper aging process of Cu-0.33Cr-0.06Zr alloy after solid solution treatment and cold deformation is aged at 450 ℃ for 2 h.After this, the conductivity and microhardness of the alloy can reach 83%IACS and 195 HV0.1, respectively.
