Abstract: The application of differential scanning calorimetry(DSC) method in the thermal physical properties test and the process formulation of metallic materials was demonstrated,including the measurement of melting temperature range,melting and crystalline enthalpy,the phase transformation temperature of titanium alloy,the homogenization treatment temperature of aluminum alloy and the specific heat capacity.The testing methods and key points of various performance parameters were introduced in details,and the development trend of the DSC technology was also forecasted.
