Abstract The stability of an iron nitride compound layer prepared by plasma nitriding of AISI D2 tool steel is investigated using in situ high‐temperature X‐ray diffraction at rising temperature up to 470°C and for an isothermal treatment at 450°C. Both kinds of experiment were carried out in vacuum. For all treatments, the iron nitride compound layer, which consists mainly of ε‐Fe3N, decomposes and forms an α‐Fe ‘black’ layer. The stability of the iron nitride compound layer is discussed in terms of the phase composition, the relative change of the lattice parameter, the nitrogen content and the decomposition kinetic. The decomposition takes place via a phase transition in two steps: (i) the out‐diffusion of nitrogen from ε‐Fe3N above an a...
