Abstract

Isoconcentration forms of crystal growth are obtained in a quasistationary approximation using a model of locally nonequilibrium diffusion in high‐speed solidification of a binary system. Four isoconcentration forms of growth (an elliptic paraboloid, a paraboloid of revolution, a parabolic cylinder, and a parabolic plate) are found for crystals that grow along a selected coordinate at a constant velocity. In the isothermal case of nondiffusion solidification, i.e., when the velocity of crystal growth is equal to or higher than the rate of impurity diffusion, these surfaces have an arbitrary configuration.
