摘要
采用单辊快速凝固方法获得了Ｃｕ－０．８Ｃｒ微晶合金，对淬态及时效处理后合金的 导电性及显微硬度进行了系统研究。研究结果表明：快速凝固Ｃｕ－０．８Ｃｒ合金经适当的时效 处理，可以在保持高导电率的前提下，大幅度提高合金的硬度。在５００℃时效３０ｍｉｎ，导电率 为８２％ ＩＡＣＳ，显微硬度为HＶ１８５。
A systematic investigation of the electrical conductivity and micorhardness has been conducted for the as - quenched and aged Cu - 0 . 8Cr microcrystal alloy produced by single - roller melt spinning method . The results show that a large increasement of microhardness can be achieved in the premise of high electrical conductivity by the proper aging treatment on the rapidly solidified Cu - 0. 8Cr alloy, and the electrical con- ductivity and microhardness are 82 % IACS and HV185, respectively, after aging at 500℃ for 30 minutes.
