A quantitative comparison between pseudo-binary and multi-component phase field models

We present a benchmark analysis to compare three different phase-field models for multi-component alloy solidification. This analysis is carried out between, two pseudo-binary approaches and one multi-component approach, with respect to solidification of a quaternary iron-containing Ti alloy. The first pseudo-binary PF model is a common approach based on the model of Karma et al. (Echebarria et al., 2004), while the second pseudo-binary PF …
