摘要

The dynamic heat capacity has been investigated upon heating and cooling in the glass transition region for the Pd₄₀Ni₁₀Cu₃₀P₂₀ amorphous alloy using a temperature-modulated differential scanning calorimeter (TMDSC). In contrast to conventional DSC results, in the experimental work a strong dependence of the temperature modulation period on the peak temperature of the imaginary part of complex heat capacity was found. This frequency dependence of the peak temperature can be well interpreted by either the Arrhenius law or the Vogel-Fulcher-Tamman (VFT) equation. The experimental results also showed that the Pd₄₀Ni₁₀Cu₃₀P₂₀ amorphous alloy was a relatively strong liquid.
