Order—Disorder Behavior of Grain Boundaries in a two Dimensional Mcdel Ordered Alloy
Published online by Cambridge University Press: 28 February 2011
Abstract
The order-disorder behavior of a Σ = 5 grain boundary was investigated using a two dimensional latice gas model and the cluster variation method. It is found that a disordered layer forms in the grain boundary region at temperatures significantly below theorder—disorder temperature for the bulk. Under certain assumptions for the pair interaction energies the model predicts grain boundary compositions different from the bulk.
