Abstract

Abstract

The microstructure, wear resistance and tensile properties of high-strength steel were tested and analyzed by adding different content of vanadium in high-strength automobile steel. The results show that the addition of vanadium is beneficial to refine the internal structure of the steel and improve the wear resistance and tensile properties of the high-trength steel. With the increase of vanadium content from 0 to 0.24%, the wear volume of the high-strength steel first decreases and then increases, the tensile strength and yield strength increase gradually, the elongation after fracture increases first and then decreases, and the wear resistance and tensile property of the high-strength steel first increase and then decrease. Compared with that without vanadium, the wear volume of the high-strength steel with 0.16% vanadium decreases by 29.6%, while the tensile strength, yield strength and elongation after fracture increase by 14.4%, 20.9% and 12.8% respectively.
