摘　　要：本文通过金相、扫描电镜及力学性能测试，研究了冷轧、退火工艺及稀土对ｃｕ－Ｎｉ－Ｚｎ合金显微结构及力学性能等的影响。研究表明，所得产品的性能接近或超过进口的同类产品，完全满足用户提出的性能要求。稀土锌白铜的冷轧总变形量不宜大于７５％，终退火温度应控制在６００～６５０℃。添加少量稀土可抑制晶粒长大，改善合金退火工艺性能及表面质量。The effect of cold rolling,anneal and rare earths on the microstructure of RE-BZn(a RE-Cu-Ni-Zn alloy)was studied by means of mechanical property tests,metallograph-ic microscope and SEM. The results showed that the developed alloy is up to or surpassesthe advanced Overseas counterpart,as well as fully satisfies user's needs,By doping smallamounts of rare earths,the grain growth may be restrained and anneal performance and sur-face qualities improved.
