| dc.description | The crystallization of a binary system is investigated in computer model which takes into account a temperature dependence of diffusion coefficient and a nonequilibrium partition of dissolved component of the alloy. The dependence of interface velocity on an undercooling at the dendrite tip is obtained during rapid solidification of Fe-B and Ni-B systems. The morphological transition which is conditioned by change from a diffusion growth regime to thermal growth at some critical undercooling is detected. This transition is characterized by discontinuous magnification of the dendrite growth velocity. Values of a critical undercooling and a growth velocity discontinuity depend both on a degree of an anisotropy of a kinetic coefficient, and on difference in energies of activation for atomic kinetics and for diffusion on an interface. | |
