Generalized cluster description of multicomponent systems
TL;DR: A general formalism for the description of configurational cluster functions in multicomponent systems is developed and a new interpretation of the Cluster Variation Method as a self-consistency relation on the renormalized cluster energies is presented.
Journal ArticleDOI
Theory of first-order phase transitions
TL;DR: In this paper, a review of various concepts about first-order phase transitions is given, with particular emphasis on metastable states near first order phase transitions, on the'stability limits' of such states (e.g., the spinodal curve of the gas-liquid transition) and on the dynamic mechanisms by which metastable state decay (nucleation and growth of droplets of a new phase).

Cluster Approach to Order-Disorder Transformations in Alloys
TL;DR: In this article, the formalism and applications of cluster expansions to the problem of ab initio calculations of thermodynamic properties of crystalline alloys are presented, and a rigorous cluster algebra that is used for systems containing an arbitrary degree of configurational order (or disorder).

Overview no. 43. Binary ordering prototype phase diagrams in the cluster variation approximation
TL;DR: In this article, the first global phase diagram investigation of f.c. based order-disorder phase diagrams with first (positive) and second nearest neighbor pair interactions is presented, which can be regarded as a precursor to more elaborate first principles phase diagram calculations.

Modeling of γ/γ′ phase equilibrium in the nickel-aluminum system
TL;DR: In this paper, a theoretical model is proposed for the determination of phase equilibrium in alloys taking into consideration dissimilar lattice parameters, where volume dependent pair interactions are introduced by means of phenomenological Lennard-Jones potentials and the configurational entropy of the system is treated in tetrahedron approximation of the cluster variation method.
