The thermodynamic behavior of the intermetallic compounds Ni3Nb and Ni6Nb7 is described in terms of sublattice models proposed by Hillert and Staffanson (1970) and Sundman and Agren (1981). The optimized parameters of the compounds and a phase diagram are calculated. The calculated homogeneity ranges of Ni3Nb at 1273 K and Ni6Nb7 at 1373 are in good agreement with the results obtained by Duerden et al. (1966). 16 refs.
