description:
	Self-affinity in deformed materials have been proposed for some time and small scale surface roughness measurments have found fractals on the deformed metals. Microbeam diffraction is a better tool for this study as it can probe misorientation generated by deformation directly in 3D. 

We have started to investigate self-affinity developed by deformation in Cu. The first experiment on a (100) single crystal indicated that fractal exists in misorientation along the loading direction at various depth in the sample. We plan to extend the study to single crystals with different orientation with respect to the loading axis. The microbeam measurements will compare with the surface roughness measurements  to be performed at ORNL.
