The techniques of ion-irradiation, nano-indentation, and electron backscatter diffraction are jointly utilized in this study, in order to investigate the orientation dependence of irradiation-induced hardening in Zr-Nb alloys. Results show that the hardness gradually decreased from (0001) corner to (10-10) and (11-20) corners, and the lowest irradiation-induced hardening was observed at [0001] orientation.
