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。
The thermodynamic calculation was used to quantitatively analyze the microstructure of ZL107 alloy under equilibrium condition. The influence of chemical composition and temperature on the microstructure of ZL107 alloy was studied. The microstructure of ZL107 alloy was observed. The results show that the precipitation temperature and amount of Al2Cu precipitates in ZL107 alloy mainly depend on the Cu content. Increasing the Cu content can increase the amount of Al2Cu phase and the precipitation temperature. Aging above 210 ° C results in a decrease in the amount of Al2Cu phase. The optimum solution temperature and aging temperature determined by thermodynamic calculation are 510 ~ 520 ℃ and 150 ~ 200 ℃, respectively, and the thermodynamic calculation results are consistent with the experimental results.
