摘　　要：采用电解腐蚀方法显示出含微量锑的铜合金中的锑脱溶相,通过SEM和EDAX表征,结果表明,锑脱溶相呈球状、粒状或条块状,粒径1～5μm,脱溶相中含稀土元素.锑以脱溶相形式析出并呈弥散均匀分布是锑铜合金具有良好综合性能的关键.The precipitation of trace element stibium in copper alloy was revealed by electrolytic etching, and characterized by SEM and EDAX. It was showed that the precipitation took the shape of sphericity, grain or piece and contained rare-earth. Diameter of the particle was from 1. 0 to 5. 0 μm. It is a key factor for Sb-Cu alloy to obtain good comprehensive property that stibium precipitation particles are even-distributed and dispersed in the matrix alloy.
