Recent works at KIMAB and Arcelor Research indicate that the mechanical properties of bainitic steels can be improved with V-microalloying. This is potentially important since there is expected to be a shift from existing precipitation hardened HSLA steels towards bainitic types as demand arises for higher strength. Although the bainitic transformation temperature is too low to promote precipitation...
Vanadium microalloying is highly effective in high strength strip steels produced by thin slab casting and direct rolled process. Because of the high solubility of V(C, N) in austenite, vanadium is likely to remain in solution during casting, equalisation and rolling. Vanadium microalloyed steels have better hot ductility and are less prone to transverse cracking than niobium containing steels. Despite...
