Full Description

This work introduces an approach to the chemical structures of grain boundaries. It presents readers with practical, experimental techniques and includes information on advances in the field. A "grain" is a portion of a material which has all of its atoms in alignment, forming a crystal structure. The boundary or interface between two grains is the grain boundary. Grain boundaries are becoming increasingly important in the development of new materials, enabling the characterization of physical and mechanical properties of materials.
