摘要
进行了含Ｚｒ的Ｃｕ－１４Ｎｉ－７Ｓｎ合金在Ｓｐｉｎｏｄａｌ分解时的硬化曲线及其ＴＥＭ研究．含Ｚｒ的合金经固溶后于４００℃时效６０ｍｉｎ可获中等强度（σｓ＝７２０ＭＰａ，σｂ＝１０５０ＭＰａ）和良好的延展性（δ＝１０％）．与不含Ｚｒ的合金对比，Ｚｒ可加速分解过程及提高分解初期的硬度．
The hardening process and TEM during spinodal decomposition of alloy Cu-14 Ni-7Sn containing Zr are investigated. A mediLlm strength (σs=720 MPa, σb=1050 MPa)and a fine ductility (δ=10% ) can be obtained when the solid solution Zr in the alloy is aged afout 60 ruin at 400℃, comparing with the alloy without Zr, decomposition is speed up and the hardness at the begining of decomposition is raised.
