In the previous study, effects of titanium (Ti) and chromium (Cr) concentrations on microstructures and mechanical properties of high-purity vanadium (V) alloys were investigated. On the basis of comparable tensile properties with the reference V-4Cr-4Ti alloy, alternative compositions with low-Ti and high-Cr levels were selected. In this study, it is to further clarify the ion irradiation effects on those candidate high-purity vanadium alloys, and the microstructural evolution and irradiation hardening after ion irradiation at elevated temperatures have been investigated.
