Effects of applied load on formation and reorientation of zirconium hydrides: A multiphase field modeling study
The effects of applied load on the formation and reorientation of deltahydrides in alpha-zirconium matrix are studied by a multiphase field model. Simulations with only one hydride seed indicate that the hydride reorientation occurs only when a tensile or compressive strain of ~0.02 is applied along [112-0] (hoop or circumferential direction) or [0001] (radial direction aligned with the basal pole direction), respectively.
