N2 - Thermophysical properties of liquid alloys are usually difficult to measure, especially for high melting point and reactive alloys. In this work, the surface tensions of superheated and undercooled liquid Ti 55Al45, Ti50Al45Nb5 and Ti45Al45Nb10 alloys are determined by using oscillating drop method under electromagnetic levitation state. The experimental results of Ti-Al and Ti-Al-Nb alloys display linear temperature dependence. The maximum undercoolings of 259 (0.143T L), 268 (0.146T L) and 275 K (0.147T L) are respectively achieved for these three alloys. Furthermore, the viscosities of liquid Ti55-x Al 45Nb x alloys are also derived from the experimental results.
