摘要
通过热力学计算研究了某厂HRB400钢中氮的溶解热力学及V、Nb合金含量对N溶解度的影响,研究结果表明:添加钒铌可有效提高氮的溶解度,但随着其含量的增加氮溶解度并不是单调递增的;以目前成品钢合金含量(质量分数)水平(V0.02%、Nb0.03%),添加铌比钒对提高氮的溶解度更有效.
The solubility of nitrogen and the influence of the content of vanadium and niobium alloy on the solubility of nitrogen in HRB400 were studied by thermodynamic calculation. The results show that the addition of vanadium and niobium can increase the solubility of nitrogen without monotone relationship,and as the current content of alloy element in steel( V0. 02% 、Nb0. 03%),niobium is more effective to improve the solubility of nitrogen.
