It was indicated by the CALPHAD that the solute content at the end point of primary solidification changes synchronistically with the start point, solute content in dendritic arm and the partition coefficient increase with the solid fraction. Simple Scheil equation was shown to be able to calculate the eutectic amount on the base of partition coefficient calculated by thermodynamics, its prediction for the different solutes is self--consistent and agreeable with the CALPHAD. The eutectic amount and SDAS was measured in DC experiment and compared to model value, it was shown that the experimental data are in agreement with the model prediction.
