Coordination Spheres Effect On RecompositionAtoms In AB Alloys
Keywords:coordination Spheres, Micro domain, Clusters, Segregations.
This study focused on the variation of the long-range order parameters with temperature for nine coordination spheres. The computer simulation results showed several mechanismsof atoms disordering. These mechanisms are represented in: (Substitution point defect, Clusters and Segregations, Micro domain, Antiphase order and Antiphase boundaries.
As the number of coordination spheres increase, the interatomic interaction increase with a decrease in the ordered phase stability. In the initial stages of the computer simulation two phases in the alloy is found, an ordered phase of long-range order and ordered phase of antiphase domain. In final stages an ordered phase of short –range order is found.
