| Abstract: | The specific heat capacity of NiTi alloy was determined by employing modulated differential scanning calorimeter (MDSC). The transformation temperatures were investigated with different heating rate. The temperatures of NiTi wire, when heated by electric current, were also calculated by using the specific heat capacities determined directly from the experiment. The results may provide meaningful information for calculating the temperature field of heated NiTi alloy scientifically and efficiently. |
