Abstract

Shear samples with special geometry were produced from high purity nickel and copper in order to study the deformation mechanism in the saturation region of severely plastically deformed metals. The shear samples, pre-deformed by high pressure torsion, were tested in situ at room temperature. Electron back scatter diffraction and back scatter images were used to characterise the change in micro-texture and microstructure after the shear deformation. The experiment revealed that almost all grains were sheared simultaneously, while at higher shear strains the formation of micro shear bands were observed.

Keywords: High pressure torsion; Nickel; Copper; Ductility
