Table 4-12: Intensity and d-spacing data in the as-received condition of the material and after hydride precipitation
under a tensile hoop stress. Only data of those precipitates formed in αZr grains of the most important
orientations are listed. A 225 MPa tensile stress was applied along the hoop direction during hydride
precipitation, resulting in some fraction of the total number of hydride precipitates to reorient in the radial
direction.
