| Abstract | ||
| Computer simulation was used to study the fine structures of 2D- square lattice. The temperatures used in the experiment was below the TC = 770k. Within this range of temperatures, the 2D- square lattice through a chain of successive non- equilibrium configurations which is achieved through the diffusion of atoms into vacant places of lattice .The equilibrium state has been obtained by averaging a number of runs (15-16) million time steps. In equilibrium state of lattice the results showed the existence of different kinds of the fine structures (microdomains, clusters, segregations and antiphase domain boundaries). At a temperatures above TC, clusters and segregations appear and the concentration of atoms in clusters was 0.5 and in segregation 0.1. Also we noticed the changes in microdomains sizes with temperatures. | ||
