X-ray microbeam measurements of long range internal stresses in commercial purity aluminum processed by multiple passes of equal-channel angular pressing
X-ray microbeam measurements of long range internal stresses in commercial purity aluminum processed by multiple passes of equal-channel angular pressing
X-ray microbeam diffraction was used to measure long-range internal stresses (LRISs) in the grain/subgrain interiors of commercial-purity aluminum processed by equal-channel angular pressing for up to eight passes. The LRIS values at +4.9° 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.

Abstract
X-ray microbeam diffraction was used to measure long-range internal stresses (LRISs) in the grain/subgrain interiors of commercial-purity aluminum processed by equal-channel angular pressing for up to eight passes. The LRIS values at +4.9° 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.
