提出了一种多组分体系扩散控制相变的定量相场模拟方法。从CALPHAD热力学和DICTRA动力学数据库的输入，在实验相关的长度和时间尺度上模拟α沉淀在Ti-Al-V中的生长和溶解。结果与DICTRA模拟结果吻合较好。(C)2003 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
A method for quantitative phase field modeling of diffusion-controlled phase transformation in multicomponent systems is demonstrated. With inputs from CALPHAD thermodynamic and DICTRA kinetic databases, the growth and dissolution of alpha precipitates in Ti-Al-V is simulated on experimentally relevant length and time scales. The results agree well with DICTRA simulations. (C) 2003 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
