Modeling of directional solidification on an atomic scale
چکیده انگلیسی

Kinetic modeling of directional solidification on an atomic scale has been carried out by the Monte Carlo method for the model of lattice liquid. Presence of vacancies in the melt that realizes diffusion of the components is taken into account. Activation energies for the interexchange between the atoms and the vacancies were calculated after counting all the nearest neighbors of both. Rates of development of distortions with different wavelengths in initial interfaces have been determined. Chemical diffusivity and surface energy were determined for the model under consideration. Particularities of cellular structure of the interface at very high pulling velocities have been studied.
