摘要

将Ce

Ce基混合稀土及重稀土钇加入ZA2 7合金中

都可使合金性能优化

其中以Ce为最好

Ce在ZA2 7合金中适量加入时

能促进组织细化和调幅分解

从而使合金的韧度、阻尼性能及耐磨性能得到显著增加。冲击韧度、阻尼性能从铸态的 2 1.5J/cm2

0 .478× 10 - 3

提高到 48.3J/cm2

1.3 4× 10 - 3

人工时效的从 80 .0J/cm2

1.78× 10 - 3 提到 12 5J/cm2

3 .15× 10 - 3 。给ZA2 7合金使用开拓了新的途径

Abstract

The proper addition of Ce into Z-7 alloy can promote t he refinement of the microstructure and amplitude decomposition effectively so a s to significantly improve the toughness

damping property and wear resistance o f the Z-7 alloy. A new frontier for application of the Z-7 alloy was developed .
