Examination of dislocation substructures in fatigued Cu using electron channelling contrast imaging
For flaw-free smooth copper single crystals, nucleation of fatigue cracks is generally associated with PSBs emerging at the free surface once stress saturation has been established. In the early stage of crack growth fatigue cracks run along PSBs (stage I). After a few tens of microns the crack devi...
