Abstract

Considering the effects of temperature and composition, a phenomenological description of lattice parameters in solid states was developed. The lattice parameter of the pure element is modeled under the assumption of a linear temperature dependence of thermal expansion, while the lattice parameters of substitutional solid-solution phases are treated similar to the Gibbs-energy modeling in the CAL-PHAD (CALculation of PHAse Diagram) approach. Using this model, the lattice parameters of the γ and γ′ phases in the Ni-Al system were analyzed and the model parameters were evaluated. The calculated lattice parameters and mismatches show good agreement with existing experimental data.
