Crystal structures of (a) α-Fe (b.c.c. structure, a_α = 2.866 Å, space group $[Im\bar 3m]$ ; Straumanis & Kim, 1969

) and (b) γ′-Fe₄N (f.c.c.-like structure with N ordering making the translation lattice primitive, a_γ′ = 3.790 Å, space group $[Pm\bar 3m]$ ; Jack, 1948

). (c) Bain distortion sketched for the α →γ′ transformation.
