| 摘 要： | 研究了CU-1型钇基重稀土对Be-Cu合金性能的影响。结果表明:Be-Cu合金经过微量CU-1型稀土的微合金化处理后,其显微硬度、耐磨性和耐腐蚀性均有不同程度的提高,热膨胀系数有所下降;随着稀土加入量的增加,Be-Cu合金的显微硬度逐渐提高,磨损量和平均腐蚀速率逐渐降低,热膨胀系数先减小后增大。

| Abstract: | The influences of CU-1 Y based heavy rare-earth elements on properties of Be-Cu alloy were studied.The results show that tiny RE addition can improve microhardness,wear resistance and corrosion resistance of the alloy in some extent and reduce the coefficient of thermal expansion of the alloy.The microhardness of the alloy increases with the increase of RE addition,but the wear loss,the corrosion rate and the coefficient of thermal expansion of the alloy decrease as Re addition increases.When Re addition increases further to 0.2%,the coefficient of thermal expansion rebounds. |
