The micro-structure and mechanical properties of three high vanadium steels rolled in laboratory were investigated.The precipitation of V(C,N) was studied through TEM.The results showed that the single-phase ferrite matrix microstructure and high yield strength could be obtained.Carbon was completely combined with vanadium in the experimental steels,so single-phase ferrite and the optimal precipitation hardening effect was acquired.The maximal yield strength of test steel was 525 MPa.The maximal increase of strength caused by V(C,N) precipitates was 244 MPa for C3 steel.The interphase precipitation is easy obtained in high vanadium steels and the diameter of V(C,N) is about 4~10 nm.
