Additional study of the orientation of zirconium hydride platelets in thin-walled Zircaloy tubing is being conducted to define the relationship of the fabrication techniques and associated Zircaloy structures to the susceptibility of the tubing to preferred hydride orientations. Second, the work will assess qualitatively the effects of oriented hydride platelets on the mechanical behavior of tubes under several stress conditions. The first stress orientation tests were run on circumferential specimens from the six types of tubing. Work was also begun on the preparation of specimens for texture measurements by x-ray diffraction. Since the final texture results were approximately two months away, the primary textures of the tubing were estimated by analysis of previously published texture data and the anisotropy of strain behavior during tensile tests. These preliminary data indicated that the susceptibility to stress orientation of the hydride platelets varied widely between tubing with similar textures and/or fabricated by nominally similar processes.
