Abstract

This work reports the application of X-ray microbeam diffraction to quantifying grain subdivision processes in copper. Polychromatic synchrotron X-radiation was used to study samples in the asreceived (low deformation) and 100% torsion strained material. The large range of domain disorientations (within individual grains) observed in the highly strained material agrees with results on other f.c.c. materials obtained by electron beam methods; it is not surprising, therefore, that models of texture development which do not include this effect predict too rapid sharpening of preferred orientation compared to experimental pole figures.
