Frequency dependence of heat capacity of the Pd 40 Ni 10 Cu 30 P 20 amorphous alloy by temperature-modulated calorimetry. Hu, X. & Li, Y. Technical Report 2000. Paper Website abstract bibtex The frequency dependence of the heat capacity in the glass-transition region of Pd 40 Ni 10 Cu 30 P 20 was studied by temperature-modulated dierential scanning calorimetry (TMDSC) during slow heating and cooling. Such data for low frequencies between 0.1 and 0.01 Hz are not available, especially for metallic glasses. A crossover between mixed static/ dynamic and purely dynamic response signals was observed for the lowest frequencies between 1/80 and 1/100 s À1 , which allows a direct determination of the average relaxation time at a given cooling rate during the static glass transition. Further, these results were used to evaluate the experimental parameters necessary to truly separate the static and dynamic response in low-frequency modulation calorimetry experiments to obtain the moduli of the dynamic speci®c heat.
