ANALYSIS OF HEAT CAPACITIES OF METALLIC GLASS ALLOYS Cu55Hf45xTix
We have investigated the low temperature heat capacity of Cu55Hf45‐xTix metallic glasses in the entire range of Ti concentrations, x=0‐45. We have established the most appropriate procedure for the analysis of data and for the estimate of low temperature electronic and phonon contributions. Both contributions exhibit monotonous Ti concentration dependence, demonstrating that there is no relation of either the electron density of states at the Fermi level or the Debye temperature to the increased glass forming ability (GFA) in the Ti concentration range x=15‐30. Our results indicate that the thermodynamic parameters (e.g. reduced glass temperature) remain the most assertive indicators of GFA for bulk metallic glasses. However, we discuss the possibility to correlate more subtle glass‐like contributions to the heat capacity, such as the Boson peak, with GFA.
