Abstract
The fatigue resistance characteristics of an aluminum-based experimental dispersion-hardened composite material obtained by internal oxidation are investigated. Fatigue tests are carried out under loading by a “soft” scheme of cantilever bending of cylindrical rotating samples under symmetric-cycle conditions. The structural and deformation features of the behavior of the material during cyclic deformation are studied by optical direct, digital, and scanning electron microscopy. The fatigue resistance characteristics of the composite are scattered little. The mechanism of nucleation and propagation of fatigue cracks is determined. Analysis of a fatigue fracture surface is performed.
