ABSTRACT
In this paper, the expression for the time of reaching the stationary mode of growth of secondary branches of dendritic crystals is theoretically determined. The dependences of the time of transition to the stationary mode on the Peclet growth number and the tip growth rate for nickel and succinonitrile dendrites are plotted. It was shown that during high-speed crystallization, the secondary branches of dendrites enter the steady-state growth mode faster than in the case of low-speed crystallization. The growth of the secondary branches of dendrites can almost always be considered stationary in cases of low-speed, moderate and high-speed crystallization.
