使用电磁悬浮振荡滴技术非接触式测量液态铝-金二元合金的表面张力γ。数据是在抛物线飞行活动期间在地面和微重力下进行的实验中获得的。对于所有样品和所有组合物，表面张力随温度线性降低。在 1400 K 时，γ 随着 Al 浓度的增加单调减小。从实验数据来看，化合物形成的特征（例如等温表面张力的最大值）并不明显。结果与使用次正则解近似的 Butler 和 Chatain 模型非常吻合。
The surface tensionsγof liquid Al–Au binary alloys are measured contactlessly using the oscillation drop technique of electromagnetic levitation. Data are obtained in experiments performed on ground and in micro-gravity during a parabolic flight campaign. For all samples and for all compositions, the surface tension decreases linearly with temperature. At 1400 K,γmonotonously decreases with increasing Al concentration. Features of compound formation, such as a maximum in the isothermal surface tension, are not evident from the experimental data. The results are in good agreement with the Butler and the Chatain model both using the sub-regular solution approximation.
