Abstract: A model for dendrite growth during rapid solidification was established on the basis of BCT model and marginal stability criterion through modified Peclet numbers.Taking into account the interaction of diffusion fields, including solute diffusion field and thermal diffusion field around the dendritetip,the model obtain a satisfactory results to predict the dendrite velocity and the tipradius,which agrees well with the experimental data from references in Cu-Ni alloy.
