Abstract
Heat capacity measurements were made by using differential scanning calorimetry in the glass transition region for Se70Te30-xCdx (x = 2, 4, 6, 8, and 10) amorphous alloys which were a couple of weeks old. Specific heat values showed an extremely large increase at the transition temperature. A rescan of the samples, heated just beyond the temperature at which the endothermic spike has been obtained, revealed a normal behaviour. This indicates that these glasses relax to equilibrium within a short span of time and the huge maximum in specific heat, Cp, is a complete artifact of the thermal history of the samples. Below the glass transition the Cp values are in the classical limits of Dulong and Petit for the vibrational heat capacity of solids. The glass transition temperatures, Tg, for these compositions are decreasing with increasing Cd content and ΔCp, the difference between liquid and glass heat capacities, also shows a similar trend.
