THE ORDER-DISORDER PROCESSES IN BINARY CRYSTALS GROWING FROM THE 50% - BINARY METALLIC MELTS ARE STUDIED WITHIN TEMPERATURE REGION BELOW CURIE ORDERING POINT
Abstract
Diphase zone’s scheme is used in the case of limited spectrum spontaneous solid state particles concentration fluctuations. There have been used stationary kinetic equations, describing diphase transitional zone’s structure in the binary melt-crustal system. It has been shown in the case of finite supercoolings region completely disordered crystalline phase was formed. This is within temperature region where according to classical thermodynamics a quite ordered crystalline phase should be grown. This concerns a far order parameter for crystalline binary systems which have simple cubic lattice. It has been shown in the case of full disordering the binary crystalline phase kinetics had peculiarity namely: a mean crystallization velocity of binary crystals did some gap proportional to square degree of the far order parameter.
