Summary
The equilibrium isothermal annneals of the binary system, Y-Zr, in the solid-state region, as well as incipient melting treatments, were completed. Microscopic examinations of all of the specimens were completed, the phase relationships noted, and the final equilibrium phase diagram for the system presented. Theoretical considerations of the alloying behavior of Ce, Ti, and Cr with Y are presented, and some of the possible types of binary phase diagrams which can be expected are given. A metallographic study of the Y-H system was undertaken to check the solubility boundaries obtained from the pressure- temperaturecomposition data. Hydride specimens were produced at four temperature levels, 1112, 1472, 1832, and 2192 deg F. Compositions of H varied from the single-phase Y solid solution region to the two-phase region and into the singlephase hydride region. Metallographically, the phase relationships in the specimens examined correlated very well with the solubility boundaries determined from thermodynamic data. Photomicrographs of structures in the Y-H system are presented. (auth)
