Abstract

A thermodynamic description of the Cr-Ti system is obtained by the optimization of the available thermodynamic and phase diagram data. The Redlich-Kister polynomial is used to describe the excess Gibbs energies of the liquid, bcc and hcp phases. The sublattice model is used to describe the different types of Cr2Ti Laves phases. The α-Cr2Ti phase is described with two sublattices after the formula (Cr, Ti)2(Ti, Cr)1. The β-Cr2Ti and γ-Cr2Ti phases are described with three sublattices after the formula (Cr)2(Ti, Cr)4(Cr, Ti)6. Calculated phase diagram and thermodynamic data show good agreement with the experimental data.
