摘要：The delayed fracture resistance of pre-stressed concrete (PC) steel bar with different vanadium contents was investigated by using tensile sustained load delayed fracture test and optical microscope. The experimental results show that delayed fracture resistance of vanadium containing steels is higher than that of conventional steel 30MnSi at the same strength level and it increases with the increase of vanadium content. The improvement is resulted mainly from the irreversible traps for hydrogen and the prior austenite grain size refinement by vanadium carbide particles.
