A homogenization approach to diffusion simulations applied to alpha+gamma Fe-Cr-Ni diffusion couples
2006 (English)In: Acta Materialia, ISSN 1359-6454, E-ISSN 1873-2453, Vol. 54, no 9, 2431-2439 p.Article in journal (Refereed) Published
The diffusion of Fe, Cr and Ni in one dimension in and between one- and two-phase alpha/gamma regions was simulated using independently assessed thermodynamic and kinetic data. Simulation results compare favourably with experimental Tesults obtained previously by one of the present authors (A. Engstrom). For example, the formation of a gamma layer between an alpha and a gamma + alpha region is correctly predicted. Neither phase interfaces nor individual phases are explicitly considered; instead, locally averaged kinetic properties are used and locally minimized Gibbs energy is assumed.
