Thermodynamic Reassessment of the La-Ni System

A simple modified analytic EAM model for bcc Fe and fcc Al metals is used to calculate the lattice constant and elastic constants of ordered intermetallic alloys of FeAl. The formation energies of vacancy and antisite defects, and migration energies of FeAl in the B2 structure type are also calculated. The present calculations are quite in agreement with the experimental data and the results obtained by other authors.
