RESEARCH ON THE SAMARIUM-TYPE INTERMEDIATE PHASES OF INTRA-RARE-EARTH BINARY SYSTEMS.

Abstract

Five new 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 studies 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 correlates well with a size effect factor of the two components in each respective system. (Author)
