LOCALLY-NONEQUILIBRIUM HEAT PROCESSES AT HIGH-SPEED CRYSTALLIZATION

摘要

The properties of a phase transition front in a nonlinear medium with heat relaxation are studied. Strong rupture of a heat field serves as a model of the phase transformation zone. A new method of studying evolution of phase transition front that we propose allows to establish the peculiarities of degeneration of an oscillatory-relaxational process into quasistationary regime. The results of numerical calculations of heat transfer at high-speed crystallization are given.
