Quantitative phase field modeling of diffusion-controlled precipitate growth and dissolution in Ti-Al-V

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.
