The specific heats of liquid Ti–20at.%Al and Ti–51at.%Al alloys are determined to be 33.01±2.75 and 31.27±2.91 J mol−1 K−1 in the stable superheated and metastable undercooled states by using an electromagnetic levitation drop calorimeter. The experimental temperature ranges are 1733–2133 K and 1511–1948 K, and maximum undercoolings of 230 (0.12 T L) and 242 K (0.14 T L) are achieved, respectively. On the basis of the experimental results, the specific heat dependence on the composition is obtained for binary Ti–Al alloys.
