测定了液态Ti 90 Al 6V4的表面张力。样品已通过电磁悬浮进行无容器处理，这允许在过冷温度区域处理高反应性材料和测量。数字图像处理的使用允许识别振荡模式并从l = 2和m = 0、m = 2振荡模式计算表面张力。数据的线性最小二乘拟合显示以下温度依赖性：
γ = 1.389 ± 0.09 − 9.017 × 10−4 ± 5.64 × 10−5（T − 1660°C）[N m−1]
AbstractThe surface tension of liquid Ti90Al6V4 was measured. The samples have been processed containerlessly by electromagnetic levitation, which allows the handling of highly reactive materials and measurements in the undercooled temperature region. The use of digital image processing allows the identification of oscillation modes and calculation of the surface tension from the l = 2 and m = 0, m = 2 oscillation modes. A linear least squares fit to the data showed the following temperature dependence:
γ = 1.389 ± 0.09 − 9.017 × 10−4 ± 5.64 × 10−5(T − 1660°C) [N⋅m−1]
