The Vickers hardness numbers (VHNs) of annealed and recrystallized vanadium and V-(0-15)Cr-(0-5)Ti-(0-1)Si alloys were determined at 25{degrees}C. The relationship between the VHN and the tensile strength of these materials previously reported by Loomis et al. are presented in this report. These results show that the VHN, yield strength (YS), and ultimate tensile strength (UTS) of V-(0-15)Cr-5Ti alloys at 25{degrees}C have a similar dependence on Cr concentration and that the VHN, YS, and UTS of V-(0-20)Ti alloys at 25{degrees}C have a similar dependence on Ti concentration. On the basis of these results and the small size of the test specimen, it is recommended that the Vickers hardness test be utilized in the vanadium alloy development program to determine the effects of thermal-mechanical treatment, impurities (i.e., O, N, C, H, and Si), and irradiation on tensile properties of vanadium-base alloys.
