Abstract Scope |
Entropy plays an important role in thermodynamics and kinetics of phase formation and structure stability, especially in the multicomponent alloy systems including the “high entropy” alloys. However, except for the entropy of mixing, other types of entropies in these systems remain less known. In this work, using a self-consistent model, we show the relative magnitudes of the entropies including the entropy of mixing and vibrational entropy. Our results indicate that the entropy of mixing in general does not contribute significantly to the alloy systems as compared with others. We will also discuss the contributions of each type of entropies to phase stability and phase formation. |
