The specific heat capacity of undercooled liquid Ni83.5Ti16.5 eutectic alloy was experimentally determined by electromagnetic levitation and drop calorimeter techniques. It decreased from 39.39 to 38.63 J mol (1) K (1) when the liquid undercooling increased from 0 to 189 K. As for solid alloy, the specific heat capacity was measured by differential scanning calorimetry. It gradually reduced with decreasing temperature and dropped to 24.75 J mol (1) K (1) at the temperature of 293 K. In addition, the thermal diffusivity and eutectic growth kinetics of undercooled liquid alloy were analyzed in the light of the measured specific heat capacity. (C) 2017 Published by Elsevier B.V.
