Abstract

We performed scanning calorimetry measurements on four bulk metallic glass formers, Pt60Cu20P20, Pt57Cu23P20, and Zr52.5Cu17.9Ni14.6Al10Ti5. We also performed step scan measurements on the liquid, crystal, and glassy phases of each of these alloys, as well as Pd42.5Cu27Ni9.5P21. From these measurements, we calculated the heat capacity of each phase, as well as the difference in entropy, enthalpy, and Gibbs free energy between the liquid and crystal phases. We find that the heat capacity of the liquid phase in the PtxCu80−xP20 family of glass formers deviates from the commonly assumed Kubaschewski Equation, and we find evidence to suggest that the heat capacities of glass formers that have previously been measured may also deviate from the Kubaschewski Equation.
