摘要:
A generalized solute drag model for binary alloy solidification with a planar phase interface was proposed as an extension of Hillert-Sundman model. Using a new thermodynamic parameter set of the Si-As system, the present model can, with the introduction of three new adjustable parameters, fit the available experimental data of Si-9 at.% As alloy. In addition, non-solute drag models with the new set of thermodynamic parameters cannot reproduce the experimental data. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
