A FUNDAMENTAL INVESTIGATION OF THE ALLOYING BEHAVIOR OF THE RARE EARTHS AND RELATED METALS

Abstract

The phase diagram of the system, Pr-Nd, was constructed from thermal analysis and metallographic data. This system exhibits complete liquid solubility and solid solubility in both the low-temperature and high-temperature phases. Lattice parameter determinations of the low-temperature phase throughout the system are under way. Knudsen effusion studies have provided data to determine the activities of liquid solutions of Pr and Nd. Plots of the activities versus the mole fraction in the liquid indicate essentially ideal behavior for Nd and a slight positive deviation from ideality for praseodymium. Liquid density studies are currently being undertaken to gain a better understanding of the behavior of liquid alloys of Pr and Nd. (Author)
