摘要

应用热力学计算对平衡条件下ZL107合金组织进行了定量分析

研究了化学成分和温度对ZL107合金组织的影响规律

并对该合金的显微组织进行了观察。结果表明

ZL107合金中Al2Cu强化析出相开始析出温度及数量主要取决于Cu含量

增加Cu含量可以提高Al2Cu相数量及析出温度。在210℃以上时效会导致Al2Cu相数量下降。热力学计算确定的最佳固溶温度和时效温度分别在510～520℃和150～200℃之间

热力学计算结果和试验结果相符。

Abstract

Quantitative analysis of the microstructures of the ZL107 alloy under equilibrium conditions was performed using thermodynamic calculations. The effects of chemical composition and temperature on the microstructures of the alloy were investigated

and the microstructures of the alloy were also observed. The results show that the precipitating temperature and amounts of Al2Cu are controlled by Cu content

where the Al2Cu phase and precipitated temperature are increased with increasing in Cu content. However

the amounts of Al2Cu are decreased with the aging temperature higher than 210 ℃

and the optimized solid solution temperature and aging temperature are in range of 510

20 ℃ and of 150

00 ℃

respectively

through the thermodynamic calculation

which are well in agreement with experimental ones.
