COMPUTER-SIMULATION OF THE KINETICS OF PHASE-DECOMPOSITION WITH THE LL(2) TYPE ORDERING IN AN ISING LATTICE SYSTEM AT LOW-TEMPERATURE

Kinetics of phase decomposition with the L1(2) type ordering has been investigated using the kinetic Ising model with interaction up to the second nearest neighbor. In the present simulation, the relationship between the local ordered structure and the clustering was examined in detail for a rather high composition (c = 12%) at low temperature. It has been demonstrated that local ordering occurred prior to the development of clustering, and the local ordered structure in the early stage of ordering has low dimensional character.
