Abstract
The general theory of multicomponent alloys is developed taking into account the multiparticle correlations between atoms with reducible and irreducible n‐body interaction potentials. The number of components and their interaction radius are not limited. The method described is not sensitive to the crystallographic structure of the alloy. The problem is being tackled using the idea of a multiparticle entropy. The internal energy is calculated by means of the high‐temperature expansion method employing an appropriately adapted diagram technique. The multiparticle correlation functions are assumed to be additional ordering parameters.
