Five binary intra-rare-earth systems were investigated to confirm the existence of the samarium-type intermediate phase. These systems are: La--Ho, Ce- -Gd, Ce-Ho, Nd-- Gd, and Nd--Ho. The systems were studied primarily by metallography and x-ray-diffraction techniques. The limits of the single-phase terminal solid solutions and the two-phase regions were determined. Lattice parameters for the intermediate phases were determined, and the approximate composition of each was established. A complete metallographic analysis of the phase equilibria in each system is presented. The position of the intermediate phase correlated well with a size effect factor of the two components in each respective system. (auth)
