Grain boundary misorientation
WebNov 18, 2024 · Misorientation within grains increases with the introduction of plastic strain, which is often used as a quantitative measure to describe the degree of microstructure deformation [ 26 ]. However, the introduction of plastic strain can result in substructure formation associated with the rearrangement of dislocations [ 26 ]. WebVisualize the misorientation angle at grain boundaries. % define the linewidth lw = 6; % consider on Fo-Fo boundaries gB = grains.boundary('Fo','Fo'); % The following command reorders the …
