Two Cu samples: oxygen-free copper (99.99 wt% Cu) and deoxidized low-phosphorous copper (99.9 wt% Cu) were processed by equal channel angular pressing (ECAP). After the ECAP processing using 4 passes, equiaxed grains (~300 nm grain size) and elongate

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
