Abstract

Si faceted dendrites grown from the same parallel twins under different undercooling (ΔT) were observed by in situ observation, and the dependence of faceted dendrite growth velocity (Vd) on undercooling was investigated. Vd increase linearly as the increasing ΔT. The faceted dendrite growth velocity-undercooling relationship was analyzed using a model developed on the basis of theoretical dendrite growth velocity. The results obtained using the proposed model fit the experimental results well and indicate that the twin spacing markedly affects the dendrite growth velocity-undercooling relationship.
