Abstract
Durability and reliability of machines and mechanisms are determined, mainly, by their fatigue resistance as far as, in the most cases, variable load impacts on machine components. Accordingly, the problem of fatigue failure is extremely topical, still. Its complexity is connected with a wide range of factors. First of all, at cyclic load the compatibility relations of a material surface layer, which is loaded over the yield point and the elastic-loaded substrate layer, play a very important role. This fact determines involvement into plastic flow and failure of all the scale hierarchy of deformation structural levels. Reverse loading under the condition of the elastic-loaded substrate layer causes strong localization of plastic deformation in the surface layers. In the deformation localization areas the material reaches its limit state, when fatigue cracks arise and expand. The paper presents the mechanisms of fatigue deformation for technical aluminum at various fatigue stages.
