Stress-controlled fatigue tests of ultrafine-grained copper round-bar specimens were conducted. Although the crack paths inclined 45° and 90° to the loading-axis were observed in the different locations, crack faces were extended along one set of m

Fatigue tests of ultrafine grained (UFG) copper produced by equal channel angular pressing (ECAP) showed negligible enhancement of fatigue strength in high-cycle fatigue regime. This was attributed to the thermal instability of UFG microstructure; a
