Abstract

Fundamental definitions of the geometrical description of grain boundaries are firstly recalled. Then the particularities of the non-cubic systems are emphasized and the results obtained in a hexagonal material, tungsten carbide-cobalt composite are presented. Different techniques such as TEM, HREM, EDX were used to characterize the grain boundaries according to the orientation relationship, the nature of the grain boundary planes and the chemical composition of the grain boundaries.
