It was established by a numerical experiment that the mean size of the nitrides of Fe−Cr, Fe−Ti, and Fe−Mo alloys and the distance between them tend toward attaining the equilibrium value determined by the temperature of the process. When the nitriding temperature is increased and the diffusion coefficient and the content of the alloying element in the alloy are larger, the time required for attaining the equilibrium state is shorter.
The effect of coalescence on the dispersity of nitrides in iron-chromium and iron-titanium alloys is negligibly small, and in iron-molybdenum alloys the coalescence of nitrides leads to the degree of their dispersity becoming smaller.
