WebABSTRACT. Basically three different types of interface are important in metallic systems: 1. The free surfaces of a crystal (solid/vapour interface) 2. Grain boundaries (α/α … Webcrystal structures provided the interface is coherent. Consider a binary solution A-B, let there be an abrupt change in composition along some direction as shown below (resulting in formation of a new interface). Consider a lattice site just to the left of the interface, where the probability that it is occupied by an A atom is C α α α α C ...
