The Alignment of Low Angle Boundaries during Deformation
Two methods of automatically determining boundary alignments from EBSD maps are discussed and shown to produce comparable results. Measurements of Al-0.1Mg and IF steel, deformed at room temperature, confirm that the alignment of low angle boundaries is primarily a function of the deformation mode, rather than the crystallography. During the high temperature deformation of aluminium, the lagbs maintain a large angle of inclination to the rolling direction (>35o) even at large strains, which is consistent with the boundaries being of transient character during deformation.
