Original Abstract

The influence of annealing of ultrafine-grained copper prepared by equal channel angular pressing on its fatigue life was experimentally determined. The fatigue loading was carried out with tensile mean stress of 200 MPa. The microstructure was examined by means of transmission electron microscopy and by means of electron back scattering diffraction. Annealing was found to result in development of bimodal microstructure. The fatigue performance of this structure is worth than that of original ultrafine-grained structure.
