Морфологические свойства линии роста двухмерного дендрита в переохлажденном расплаве

Abstract

Thermophysical and kinematic aspects of crystal growth in an unicomponent supercooled melt are considered. The analytical description of the dendrite side-branch fore runners in the finite neighbourhood of the dendrite tip is given. Nontrivial behavior of sharp edges and inflexion points on the planar two-dimensional growth line is established. Extreme properties of entropy production on the crystallization boundary at locally non-equilibrium heat transfer are studied.
