TY  - JOUR
AB  - The phenomenon of stress-reorientation has been investigated using in situ X-ray diffraction during the thermomechanicalcycling of hydrided Zircaloy-4 tensile specimens. Results have shown that loading along a sample’s transverse direction(TD) leads to a greater degree of hydride reorientation when compared to rolling direction (RD)-aligned samples. Theelastic lattice micro-strains associated with radially oriented hydrides have been revealed to be greater than those orientedcircumferentially, a consequence of strain accommodation. Evidence of hydride redistribution after cycling, to α-Zr grainsoriented in a more favourable orientation when under an applied stress, has also been observed and its behaviour hasbeen found to be highly dependent on the loading axis. Finally, thermomechanical loading across multiple cycles hasbeen shown to reduce the difference in terminal solid solubility of hydrogen during dissolution (TSSD,H) and precipitation(TSSP,H).
