Abstract | ||
This study focusedon the variation of the long-range order parameters with temperaturefor nine coordination spheres. The computer simulation results showed several mechanismsof atomsdisordering. These mechanisms are represented in: (Substitution point defect, Clusters and Segregations, Micro domain, Antiphase order and Antiphase boundaries. As thenumber 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 anordered phaseof short –range order is found. | ||
