Essay

The process of phase formation in the region of the initial diffusional contact of copmonents. To describe the process of phase formation at the initial stage of interdiffusion in coherent nanosystems for both the phase transitions of the first and the second order. The methods of investigation are the methods of computer modeling of a crystall alloy at the atomic level. The possibility of nonmonotonous regime of ordering in the field of concentration gradient is predicted. The size dependence of effective surface tension for nanoparticles of ordered phase as a result of correlation of theirs size and shape is established. The exsistence of two-stage growth of new phase in multylayers for the case of diffusive unpenetrable phase is established, what corresponds to latteral and normal regimes. The application field is nanotechnologies
