Abstract
X-ray microbeam diffraction was used to measure long range internal stresses (LRIS) in the grain/subgrain interiors of commercial purity aluminum processed by equal-channel angular pressing for up to 8 passes. The LRIS values at +4.9o off the axial (pressing) direction show only a slight increase with increasing numbers of passes. The normalized stress remains approximately constant at ≈ 0.10 of the flow stress.
