Abstract

The research, production, and application of V-N microalloyed high strength rebars in China were reviewed. Enhanced nitrogen in vanadium-containing rebars promotes the precipitation of fine V(C, N) particles, and markedly improves the precipitation strengthening effectiveness of vanadium. Therefore, vanadium added to V-N microalloyed rebars can be reduced by 40% compared to the same strength level of vanadium-containing rebars.
