Abstract

The thermophysical properties of undercooled liquid alloys at high temperature are usually difficult to measure by experiment. Here, we report the specific heat of liquid Ti₄₅A_l45Nb₁₀ ternary alloy in the undercooled state. By using electromagnetic levitation technique, a maximum undercooling of 287 K (0.15 T _L) is achieved for this alloy. Its specific heat is determined to be 32.72 ± 2.51 J mol^-1 K^-1 over a broad temperature range of 1578-2010 K.
