摘要

Based on the analysis of forces using interfacial energies acting on particles at a solid/liquid interface, we propose a new particle transfer theoretical model. This model can predict the behavior of particles at the interface. The main concept of this model is proved by the mutual wetting behavior among the solid, liquid and particle phases. Of the contact angle between a solidification front and a particle is less than 90°, the particle can be engulfed into the solid, and if the contact angle is greater than 90°, the particle would be pushed.
