Equilibrium concentration of dissolved nitrogen (in wt.%, rounded off to three decimal places) in pure liquid iron, exposed to atmospheric air at 1873 K, is
Given: Sieverts’ law constant as a function of temperature (T; in Kelvin) is log10 K [N] = [-518/T- 1.063], where 𝐾[N] has the dimension of 𝑎𝑡𝑚-(1/2).
Assume [hN] =[wt.% N] , where [hN] is the activity of nitrogen with respect to 1 wt.% Henrian standard state.
