摘要
本文对真空熔铸含Ｍｎ量为０．４６ｗｔ％的Ｃｕ－１５Ｎｉ－８Ｓｎ合金的时效硬化、形变时效使化过程及其组织变化作了研究。实验证明：（１）０．４６ｗｔ％Ｍｎ固溶于Ｃｕ－１５Ｎｉ－８Ｓｎ合金中，（２）含少量Ｍｎ的合金的时效硬化、形变时效硬化及组织变化的基本特征与不含Ｍｎ的Ｇｕ－１５Ｎｉ－８Ｓｎ合金相类似，但少量Ｍｎ延缓合金的时效、形变时效过程，增加硬化效果。
The age-hardening,thermomechanical age-hardening characteristics and structural change of vacuum-melting and casting Cu-15Ni-8Sn alloy with 0.4wt%Mn have been investigated. The results show:(1)the 0.46wt%Mn present in solid solution(2)the age-hardening,thermomechanical age-hardening characteristics and structural change characteristics of of alloy with Mn is similar to that of alloy without Mn, small amounts Mn suppresses age-hardening and thermomechanical age-hardening process but increases hardening effect.
