Abstract
The paper discusses the influence of ultrafine-grained structure of martensitic and austenitic steels on diffusion processes at low-temperature ion nitriding. The microstructure of ultrafine-grained steels was analysed before and after nitriding. Depth distributions of microhardness are given depending on the class and structure of steels. The study proves that ultrafine-grained structure of steels obtained by high pressure deformation by torsion allows an increased growth rate of the diffusion layer at nitriding.
