Description
Summary:In this study, scanning electron microscopy was used to follow the microstructure development in 93/7 brass that had been homogeneously cold rolled to different plastic strains. Crystallographic (Kohlhoff) etching was employed to follow rolling texture and microstructure development. Deformation banding or orientation splitting is shown to play an important role in plastic deformation and by this means complete rolling textures were observed in a few adjacent grains. Mechanical twinning causes scattering from the texture fibers. Deformation bands are sensitive to the geometrical configurations of grain boundaries and hence modify both microstructures and the related textures. On the mesoscale, theoretical analysis gives a reasonable explanation of the experimental results.
