Abstract:

In this paper a new method is presented for estimating thermodynamic properties of binary intermetallic compounds through fitting a simple correlation equation. Entropies and heat capacities of some binary intermetallic compounds are calculated by this new method. The result shows that this method is simple, and it can guarantee an acceptable accuracy.
