The roughness of grain boundaries in partly recrystallized microstructures has been quantified. Effects of material and processing parameters on the roughening behavior have been statistically investigated. Parameters are sample purity, deformation strain and boundary migration direction in two cold rolled aluminum samples. The results show that particle pinning is not the main reason accounting for recrystallization boundary roughness in the present samples. The roughness is however shown to relate to the deformation microstructure and possible effects of migration rate are discussed.
Grain boundary roughness in partly recrystallization microstructure is quantitatively characterized using a morphological variable termed area integral invariant. Effects of material and processing parameters on grain boundary roughening are evaluated using the roughness parameter.Figure optionsDownload high-quality image (469 K)Download as PowerPoint slide
