铜铬合金等径角挤压后的组织与性能

Microstructure and Properties of Cu-Cr Alloy Processed by ECAP

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.
