Vanadium alloy is one of the most important candidate structural materials for a fusion reactor. Its main advantages over other candidates are its low activity feature and feasible properties at high temperature. However, vanadium is easily oxidized at high temperature to form a non-protective surface film of V2O5. Oxygen concentration would thus get high and the properties get worse in not only the loss of the ductility but also the enhanced hydrogen embrittlement by the oxidation.
