Shear banding and the formation of Goss and brass texture components in C-{112}<111> oriented silver single crystals
The microtexture components of `brass-type' shear bands developed by plane strain compression in twinned C-{112}<111> oriented silver single crystals have been characterized in detail by SEM/EBSD. The twinned matrix exhibits three different reorientation tendencies : 1) a general lattice rotation of the twinned matrix towards the {111}<112> position ; 2) a crystal lattice rotation, within the shear bands, around TD towards {110}<001> which favours the operation of two highly stressed coplanar slip systems of {111}<101> type ; 3) the formation of near S-Brass {123}<634>-{011}<112> texture components by non-equilibrium slip within the shear bands. In low SFE materials the strong intensities of these components result from a saturation of the microstructure by shear bands.
