The old difficulty of reconciling the structure of ordinary grain boundaries with their properties is removed if we accept the concept that grain boundaries have a general structure which accounts for certain properties (e.g. energy, equilibrium, segregation) and also a defect structure, superimposed on the general structure, which accounts for other properties (e.g. sliding, emission and absorption of vacancies).
