Abstract

Experimental data from microwave postdischarge nitriding during growth of a γ′ layer have been used to estimate the diffusion coefficient of nitrogen in γ′-Fe₄N_1-x. Based on a model obtained from a mass balance and considering thermodynamic equilibrium at the γ′/α interface during growth, a self-diffusivity of nitrogen in γ′ was obtained: D^γ′_N = 3.83 × 10^-10exp(-93 500 J/RT) (m² s^-1), for 773 K<T<843 K.
