Deformed alloys Fe-Сr; Fe-Cr-Ti. Investigation of the phase formation in the near-to-surface layers under C and N saturation. Complex of the classical and modern methods of investigation was used. Diffusion layers with optimal properties are formed after deformation 20-30% and saturation in the mixture os 90 vol.% ammonia and 10% propane-butane. Alloying by Cr 0.5-1.5% accelerates the diffusion layers formation in the alloys after defined deformation.
