Abstract

Experiments on megaplastic deformation of magnesium at room temperature by transverse extrusion and subsequent cold rolling are described. The microstructure and mechanical properties of a 120-μm thick magnesium foil with total true compressive strain e ~ 6.0 are studied. It is shown that low-temperature annealing increases the strength and ductility properties of the specimens. The detected abnormal growth in the yield strength is explained from the standpoint of thermally activated processes of rearrangement of the dislocation structure and locking of dislocations.
