Abstract

The present paper shows the results of high temperature experiments performed on Cu single crystals. The crystals were deformed by rolling at 900°C with the rolling plane either parallel to {123} or 14° off the {111} crystal plane. In the former, slip events were evenly distributed in the samples. No recrystallization was then observed. For the crystals which were 14° off the {111} plane, the deformation was non-uniform and numerous shear bands were formed. It was found that the density of shear bands increased with strain, and recrystallization initiated within the shear bands. A model of dynamic recrystallization in crystals deforming by the shear band mode is discussed in terms of the structural features revealed by optical and electron microscopy.
