N2 - An analysis is presented for the time-dependent solute redistribution which occurs during crystallization at constant velocity and constant temperature. The analysis is suggested to be applicable to many studies of crystallization in glass-forming systems, where solidification takes place at temperatures well above the solidus and where the solubility in the crystalline phase is quite limited. Appropriate for these situations, the usual condition of Cs = kCL is replaced by the approximate condition of Cs = Csolidus. The results indicate a concentration of the liquid at the interface which is limited only by the liquidus composition, and not by a steady-state composition of CO/k. Limitations of the present analysis for cases where the growth rate becomes concentration-dependent are discussed.
