Th-Y

Th-Y (Thorium-Yttrium) Editor The general form of the Th-Y phase diagram was determined by [60Eas]. The (aTh) + (aY) two-phase field at 900 C was reported to extend from 39.5 to 53 at.% Y. However, [60Eva] placed these boundaries at 49 and 69 at.% Y. [87Car] prefers the data of [60Eva], because higher purity specimens were used. The boundaries of solid phase transformations are schematic and have been drawn similarly to those of [60Eas].-H.O. 60Eas: D.T. Eash and O.N. Carlson, Trans. ASM, 52, 1097-1114 (1960). 60Eva: D.S.
