Abstract A model for solute redistribution in a spherical geometry is developed and applied for equiaxed solidification to determine the growth kinetics under the condition of moving boundary. By coupling with the macroscopic model for thermal calculation, the time-dependent growth rate of the advancing interface, interface concentration as well as the concentration distribution in both the bulk liquid and solid can be accurately calculated. The relationships between the growth rate and concentration, the solidification parameters and the alloy physical properties can also be calculated.
