SLIP BAND EXTRUSION IN FATIGUED CLOSE PACKED HEXAGONAL METALS,

Abstract:

The surface topography produced in fatigued cadmium, zinc, and magnesium polycrystals is described slip band extrusions occur in cadmium and magnesium but not in zinc. The distribution of the extrusions is related to the dislocation configurations observed in these metals on the basis of these results a dislocation mechanism involving glissile dislocation dipoles is proposed to account for both extrusions and intrusions in face centred cubic and close packed hexagonal metals.
