These principles in elude heat transfer and recalescence, thermodynamics of metastable and non-equilibrium solidification, growth kinetics and solute redistribution.

Considering the appearance of solute trapping in non-equilibrium rapid solidification, its effect of solute trapping on the growth process was discussed basing on the existent eutectic models.

Research progress and the limitation of non-equilibrium effect of rapid solidification and its formation mechanism are analysised.
