In this paper, the authors studied the cycle durability of a multi-layered steel material based on stainless steels 08Cr18Ni10 and 08Cr18 at high values of stresses under the scheme of pure bending. The results showed that the cycle durability increases with increasing dispersion of the laminar structure. In addition, the authors studied the fractures after fatigue failure and analyzed their microstructure. The analysis showed that the nature of the fatigue failure of a multilayer steel material depends on the dispersion of the laminar structure.
