| 摘 要： | 采用等径角挤压（ECAP）对铜铬合金（Cu／3．75%Cr）进行加工，并进行了金相及扫描电镜分析。结果表明：ECAP导致材料晶粒细化十分明显，铬在合金中仍以颗粒状均匀分布。同时，ECAP加工后铜铬合金硬度和抗拉强度也有很大提高。

| Abstract: | The method of equal channel angular pressing(ECAP)was used in the manufacture process of the alloy Cu-Cr(Cu/3.75%Cr).The metallographic and SEM examination were performed.The results indicate that the grain size was obviously refined,and the Cr precipitates in the Cu-Cr were distributed well.The hardness and tensile strength of the copper alloy increased a lot. |
