Thermodynamic assessment of the Ni-Ti phase diagram

Abstract

A new assessment of the thermodynamic properties of the stable phases of the Ni-Ti system is presented, based on the experimental thermochemical and phase diagram data from the literature. Suitable sublattice models are used to describe the non-stoichiometries of NiTi and Ni3Ti. The calculated phase diagram and the thermodynamic properties show good agreement with the experimental information.
