Abstract

Temperature-modulated differential scanning calorimetry (TMDSC) is based on conventional DSC but with a sinusoidally modulated temperature path. Our simulations of TMDSC signals prove that the frequency correction of non-reversing heat flow can give a master curve within a certain range of frequencies. This frequency range is dependent not only on the measurement parameters such as linear heating/cooling rate and frequency and amplitude of the modulation, but also on the previous thermal history before the TMDSC measurement. The frequency correction for the reversing heat flow gives more insights about the glass structural response to thermal treatments.
