The effect of nickel on the solubility of Fe_4N and the diffusion of nitrogen in α-iron was investigated by the internal friction technique. By applying a magnetic field in excess of 80 Oe on the specimens, the magnetoelastic damping could be eliminated and the background damping was decreased. The Snoek peak of nitrogen in iron-nickel alloys might take place due to a single relaxation mechanism. The diffusion of nitrogen in α-iron is independent of the presence of nickel, expressed by the next equation ; D=2.2×10_^<-3> exp(-18, 000/RT). The addition of nickel renders a decreasing effect for the solubility of Fe_4N, but an increasing effect for the heat of solution of Fe_4N in α-iron.
