Original abstract
The mechanical properties and fatigue behaviour of ultrafine-grained (UFG) materials during cyclic loading are by far not well described and understood. This paper presents experimental results of fatigue lifetime and cyclic plastic properties of UFG copper prepared by means of equal channel angular pressing (ECAP) technique. It has been observed that fatigue loading did not result in a substantial change of microstructure. In spite of this it has been shown that the cyclic stress-strain response changes qualitatively in dependence on the stress amplitude. The fatigue behaviour, cyclic plastic strain localization and structural stability are discussed.
