N2 - A unified solute diffusion model is proposed for columnar and equiaxed dendritic alloy solidification, in which nucleation, growth kinetics and dendrite morphology are taken into account. Various applications to a uniformly solidified system are demonstrated, with emphasis on three special cases: complete solute mixing in the liquid, columnar growth with significant dendrite tip undercooling, and equiaxed dendritic growth. Theoretical predictions of microsegregation, eutectic fractions and cooling curves are compared with a number of previous theoretical and experimental results, and good agreement is found.
