利用Jmat-Por软件模拟计算Al-Cu合金的凝固路径及合金中Al3(Zr,Ti)相的生成温度、生成数量随Zr和Ti元素含量变化的规律。结果表明,计算机模拟与DSC和微观组织测试结果基本一致;Al3(Zr,Ti)相的百分含量随着Zr和Ti含量的增加而逐渐上升,同时Al3(Zr,Ti)相的生成温度也随着Zr和Ti含量的增加而逐渐增加;当两种元素的含量在0.20%~0.45%之间变化时,这种相的形成温度区间为754~816℃。
Using Jmat-Por software to simulate the Al-Cu alloy solidification path and alloy Al3 (Zr, Ti) phase formation temperature, the amount generated with the Zr and Ti element content of the law. The results show that the computer simulation is basically consistent with the results of DSC and microstructure test. The percentage of Al3 (Zr, Ti) phase increases with the increase of Zr and Ti contents, and the formation temperature of Al3 (Zr, Ti) With the content of Zr and Ti increasing, the formation temperature range of this phase is 754 ~ 816 ℃ when the contents of two elements vary from 0.20% to 0.45%.
