Structure of Multicomponent Materials

Abstract

This chapter discusses several aspects of the structure of multicomponent high-entropy materials: the fundamental thermodynamics of single-phase and multiphase multicomponent materials; the atomic and electronic structure of multicomponent single-phase solid solutions; and defects such as vacancies, dislocations and grain boundaries in multicomponent single-phase solid solutions, as well as their effect on fundamental properties such as atomic diffusion, twinning, plastic flow and recrystallisation. It concentrates on the available experimental evidence for the structure of the materials, supported where appropriate by the use of thermodynamic and atomistic computer modelling techniques.
