Abstract

FURTADO, Alexandre Ferreira. Simulation of microstructures of ternary alloys via Phase Field method. Matéria (Rio J.) [online]. 2007, vol.12, n.4, pp.602-611. ISSN 1517-7076.  http://dx.doi.org/10.1590/S1517-70762007000400009.

A phase field model for solidification of ternary alloys is proposed. In this paper, the relations between material properties and phase-field parameters are presented. In the development of this work, the ternary-alloy solidification model for the analysis of diffusivity is employed. For two-dimensional computations, the dendritic growth is simulated for Fe-C-P ternary alloys. The change in phosphorus concentration affects the interface velocity. This change in the interface velocity is due to the small diffusivity of phosphorus during the solidification process.

Keywords : Phase Field; solidification; segregation; dendrite.
