Abstract
We analyze the enthalpy of crystallization Hx and fusion Hm, and calculate the average difference of the heat capacity between supercooled liquid and equilibrium crystalline solid ÎCave in a series of glass-forming metallic supercooled liquids. It is found that ÎCave is close to a constant 13.2Â J/mol/K which is an important feature for glass-forming metallic supercooled liquids, and there is no obvious correlation between the parameter Ï(=1âHx/Hm) and the glass-forming ability. The ratio of ÎCave to the entropy of fusion is an important parameter in determining the glass-forming ability in metallic glasses.
