摘要

摘要: 在汽车用高强钢中添加不同含量的合金元素钒，并进行了高强钢显微组织、耐磨损性能和拉伸性能的测试与分析。结果表明，合金元素钒的添加有利于细化钢的内部组织，提高高强钢的耐磨损性能和拉伸性能。随钒含量从0增至0.24%，高强钢的磨损体积先减小后增大,抗拉强度和屈服强度逐步增大,断后伸长率先增大后减小，高强钢的耐磨损性能和拉伸性能先提高后下降。与不添加钒相比，添加0.16%钒时高强钢的磨损体积减小29.6%，抗拉强度、屈服强度和断后伸长率分别增大14.4%、20.9%、12.8%。

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.
