Amorphous configurational specific heat

The Cp s curve of the reheated (control) sample is unaffected by thermal changes and consists of configurational contributions as well as those arising from purely thermal vibrations. Therefore, the vibrational specific heat, Cp,v, for the amorphous alloy is extrapolated from the Cp values in the low-temperature region and is a linear function of temperature, viz.,... 

The intermolecular potential, Eq. III.7, is not a necessary condition for Eq. III. 13. The necessary and sufficient condition is that N-1 In ZQ is a function of kTv jX only. In other words, the condition is that the ratio of the potential energy (> 0) in one configuration with the specific volume to the potential energy in another similar configuration with, the specific volume always equals (r2M) - Under this weaker condition, where the additivity of the intermolecular potential is not assumed, most relations in the present section hold. Namely, if a phase transition between crystalline and amorphous states occurs, then the (l-fs 1)th power of the transition temperature is proportional to the pressure and the latent heat is proportional to the transition temperature. In the next section we treat an Ising-Lattice model with the aforementioned similarity condition.
