摘要

以ZL101合金为基础

通过添加Cu、Ni、Mn、V、RE等合金元素

制备了改良ZL101合金

并对其高温力学性能进行了研究。结果表明

改良ZL101合金组织中由于出现了Al2Cu、Al7（FeMnSi）3、Al6Cu3Ni和AlxV3CuRE等新相

因而改善了合金的高温力学性能

提高了其服役温度

且改良合金制备工艺简单

成本低廉。

Abstract

Modified Al-Si casting alloy was prepared by adding alloying elements

such as Cu

and elevated mechanical properties of the alloy were analyzed.It is found that elevated mechanical properties of the alloy are improved as a result of creation of Al2Cu phase

Al7（FeMnSi）3 phase

Al6Cu3Ni and AlxV3CuRE phase in the microstructure

greatly raising the service temperature.In addition

the preparation technology exhibits the features of simple and low cost.
