Description

An influence of small amounts of impurity on the dendrite growth is investigated analytically and numerically. For investigations, a model for anisotropic dendrites rapidly growing in pure and binary melts is used. The dependence of the dendrite growth velocity and of the dendrite tip radius from undercooled melt from amounts of impurity is analyzed. Calculations are carried out for the pure nickel and binary nickel-zircon diluted melts. (paper)
