摘要
根据Thermo-Calc和相关文献的测试数据,推导出Fe4N在奥氏体和铁素体中的平衡固溶度公式分别为:log[N]γ=0·940-479·4/T,log[N]α=1·074-1838/T。同时考虑Fe4N的形成自由能而推导出氮(气)在奥氏体和铁素体中的平衡固溶度公式分别为:log[N]=-2·752+1321/T,log[N]=-1·560-1214/T。
According to measured solubility data of Thermo-Calc and concerned references, the equilibrium solid solubility formulae of Fe4N in anstenito and in ferrite have been derived respectively as log[N]γ = 0.940 -479.4/T and log[ N ]α = 1. 074 - 1 838/T. With considering free energy of Fe4 N fortnafion, the equilibrium solid solubility formulae of nitrogen （gas） in anstenite and in fenlte have been derived respectively as log [ N ] γ = -2. 752 ＋ 1 321/T and log[ N ]α=- 1. 560 - 1 214/T.
