The La-Y, La--Gd, and Gd--Y alloy systems were examined by conventional metallurgical research techniques. As would be expected from the similarity of the parent metals, the Gd--Y system exhibits complete solid solubility across the system in both the alpha and beta regions, with nearly perfect behavior indicated by the essentially linear plots of lattice constants and other related data, The La--Y and La--Gd systems show complete solid solubility in the high temperature bcc region, with limited solubility in the room temperature forms. In the central region of these two systems at room temperature, an ordered phase with the samarium structure is observed, Some correlation of structure and lattice constants of this phase with the properties of the related pure metals is observed.
