The surface tension and specific heat for liquid ternary Ti-6Al-4V alloy were measured by the oscillating drop method and drop calorimetry, respectively, under containerless condition over broad temperature ranges. The solidification microstructures at different undercoolings appeared as the basket-weave morphology. The relationship between dendritic growth velocity of beta phase and undercooling was determined as a power function, and the growth velocity attained 22.21 ms(-1) at the maximum undercooling of 252 K (0.13 T-L). The mechanical property of this alloy solidified at different undercoolings was determined through compression tests, while its thermal diffusivity in the solid state was measured by the laser flash method.
