Abstract We present an interpretation of the phase diagram for a binary alloy from point view reaction dynamics. consider model system in which two-component liquid is ideal solution, but solid can be non-ideal, with its non-ideality increasing reducing temperature. show how ‘batch’ evolution solid–liquid system, interfacial growth rates are proportional to free energy differences, leads set fo...

This chapter introduces calculational methods that can be used for abinitio structure prediction in multicomponent alloy systems, with an emphasis on concepts relevant to high entropy alloys. Specifically we will address density functional-based calculation of T=0K total energies. Extension to finite temperature will use cluster expansions for the energies to obtain the chemical substitution en...

We extend the two particle theory of disordered systems within the coherent potential approximation CPA to obtain weighted contributions to averaged two particle resolvents which arise from separate alloy components. Starting from first principles in a model of diagonal disorder and the single site approximation for a binary substitutional alloy A c B 1−c we extend the approach of a fundamental...
