Abstract

Abstract

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.
