摘　　要：采用物理化学定量分析技术,研究钢中氮元素对钒的碳氮化物析出的影响,以及对铁素体组织的影响。增氮对钢的强化,主要通过铁素体中的V(C,N)沉淀析出实现。增加0.014%的氮后,钢中V(C,N)的析出数量提高了72%。By using the method of quantitative physical and chemical analysis,the effect of the nitrogen on the carbonitride precipitation of vanadium was studied as well as the ferrite structure.Increasing the steel strength by adding the nitrogen,this was achieved mainly through the increase of ferrite V(C,N)precipitates.Increasing 0.014% nitrogen in steel,V(C,N)of the precipitation amount was increased by 72 %.
