The Effect on Heterogeneous Nucleation of Solute Segregation
The effect on heterogeneous nucleation of solute segregation was studied with segregating energy and segregating coefficient. The results showed that the segregating energyΔGγsegr of solute played a more vital role in the nucleating process, specially in the case that (1-k) is small. A critical criterion with the parameter was suggusted for estimating the nucleating abilitiy of the external particles in binary alloy, which had the vital theoretical or practical significance for choicing refiner.
