Abstract
A combination of ion-accelerator irradiation, nanoindentation tests, and electron backscatter diffraction analysis was utilized to probe the crystal orientation dependence of irradiation-induced hardening in a Zr alloy. The nanohardness at the [0001] orientation exhibited the highest value, which gradually decreased when the orientation deviated from the [0001] axis to the [101¯0] and 21¯1¯0 axes, regardless of the irradiation dose. Crystal-orientation-dependent irradiation-induced hardening is further confirmed. The lowest hardening was observed at [0001] orientation, and the hardening effect intensified toward the [101¯0] and [21¯1¯0] orientations, reaching the maximum at a rotation angle of ~55° with respect to [0001].
