چکیده انگلیسی
The local dislocation density near a grain boundary in hot deformed AA 3104 aluminum alloy was computed from boundary parameters obtained through transmission electron microscopy. A contour map of local dislocation content was presented to help visualize the heterogeneous deformation that arose from the interaction between dislocations and grain boundaries. The contour map shows that the dislocation density exhibits a maximum at approximately 13 μm from the grain boundary, which can be attributed to the relaxation of the pile-up stress generated in the neighboring grain.
