Nitrogen solubility in liquid Fe and Fe-C alloys has been measured by the levitation melting method under 1 atm N_2 pressure. Experiments were carried out at the temperature range of 1774-2097˚K and carbon content of 0-5.06wt%. The nitrogen solubilities measured in pure Fe and Fe-C alloys were$log(wt%N)_{Fe}=-424/T-1.129 and log(wt%N)_{Fe-C}=-[424/T+1.129+(%C)/19.14{5447/T- 0.612}+(%C)^2/19.14 2478/T-1.265]
