运用 Butler 方程, 结合 CALPHAD 优化后的过剩吉布斯自由能, 计算了 973 K 温度下, Al-Mg, Mg-Zn, Al-Zn 二元合金的表面张力. 结果表明, 在 Al 熔体中加入金属 Mg 和 Zn, 可降低该液态合金的表面张力. 在此基础上, 利用 Chou 模型计算了 Al-Mg-Zn 三元合金的表面张力. 结果表明, Al-Mg-Zn 三元合金表面张力计算值范围为 0.575$\sim $0.864 N/m, 且随着 Mg 含量的增加, 表面张力减小. 对比了二元及三元合金表面张力的计算值与实验值, 误差在 5${\%}$ 以内.

The surface tensions of the Al-Mg, Mg-Zn and Al-Zn binary systems at 973 K were estimated on the basis of Butler's equation, in combination with excess Gibbs energy parameters calculated by CALPHAD technology. The results indicated that the surface tension of Al melts decreased with increasing additions of Mg and Zn. At the same time, the surface tension of Al-Mg-Zn ternary alloy at 973 K were calculated by using Chou model. The results showed that surface tension of ternary alloy was approximately in the range of 0.575$\sim $0.864 N/m, and the surface tension decreased with addition of Mg. The estimated results of binary or ternary alloys were in excellent agreement with experimental data and the error was less than 5${\%}$.
