Query: Phase-field modelling of solute trapping during rapid solidification of
  a Si-As alloy   The effect of nonequilibrium solute trapping by a growing solid under rapid
solidification conditions is studied using a phase-field model. Considering a
continuous steady-state concentration profile across the diffuse solid-liquid
interface, a new definition of the nonequilibrium partition coefficient in the
phase-field context is introduced. This definition leads, in particular for
high growth velocities, to a better description of the available experimental
data in comparison with other diffuse interface and sharp-interface
predictions.
