Abstract

The specific heat capacity of undercooled liquid Ni_83.5Ti_16.5 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.
