摘要
采用取样法,在密封体系的MgO坩埚中研究了铁液中Al-N,Nb-N反应平衡。得到氮在铁液中的溶解平衡常数lgK=-1106/T-0.771lgK_(AIN)=-9909/T+3.81lgK_(NbN)=-34700/T+18.
The equilibria of Al-N and Nb-N in molten iron at 1600 ℃ to 1700 ℃ by using of sampling method have been conducted. The thermodynamic parameters obtained are For the reaction of 1/2N_2=[N] lgK=-1106/T-0.771 lgK_(AIN)=-9909/T+3.81 lgK_(NbN=-34700/T+18.37
