    • In Ref. 37 Ivantsov assumed that the crystal growth shape must be an isoconcentrational interface which grows under quasiequilibrium conditions. When the crystals grow under nonequilibrium conditions, and the shift from local equilibrium at the interface and in the diffusion field of bulk phases is manifested, the crystal shape must be different from Ivantsov's solution 37. In contrast with the calculations which used the Ivantsov function (see Refs. 23, 29), our unpublished results of a computer simulation based on the system of equations (2.3)–(2.5), (2.8)–(2.10), and (3.10) show that a full scenario of solute and thermal dendrites in all regions of undercoolings can be obtained. Also, we suppose that in rapid solidification the effect of growth anisotropy can influence the function ``undercooling–dendrite growth velocity'' considerably [see
