The cohesive energy and lattice parameters are fitted by the potentials, which also give good agreement with experimental values for the same properties in the phase. A second interatomic potential was developed for the Nb-Ti system via a fitting to the lattice parameters and thermodynamic properties of the disordered BCC phase. The Al and Ti potentials used here are the same as those used in our previous work to derive Ti-Al potentials based on TiAl. This allows the use of the present potentials in conjunction with those previously derived interactions to study ternary Nb-Ti-Al alloys. The potentials were used to calculate the heats of solution of Al and Ti in Nb, and to simulate the orthorhombic phase."
