Abstract A method for measuring the specific heat capacity of metal samples by CW laser heating was proposed. Heat transfer model of finite size specimen and the quasi-steady state measurement model under continuous heating were established and verified by numerical simulation with COMSOL Multiphysics software. Considering the heat loss of contact heat transfer, convection heat transfer and heat radiation in the actual measurement process, the heat loss of the measurement model was modified. The simulation results show that the deviation of the modified model is less than ±0.81% when the comprehensive surface heat transfer coefficient is less than 80W/(m2·K). The experimental measurement device was set up, 532nm CW laser was used as heating source. Titanium alloy TC4, stainless steel 316L, steel 45, aluminum alloy 7075 and copper T2 samples were processed and drilled micropore on each sample. The heated surfaces of the samples were coated with graphite and the temperature rise inside the samples was measured by using a very fine K-type thermocouple. The specific heat capacity of copper T2 was used to calibrate the system parameters. The experiment results show that the repeatability of measurement is better than 0.91%, the relative deviation between the average value of the measurement results of each metal sample and the reference value of the data manual is less than ±3.1%. The relative expanded uncertainty is evaluated to be U=3.66%(k=2).
