Microstructure, deformation behaviors and GND density evolution of Ti-Al laminated composites under the incremental compression test

On the microstructure and texture of intermetallics in Al/Mg/Al multi-layer composite fabricated by Accumulative Roll Bonding

“…In order to assess the dislocation density of the AZ31, Mg17Al12, and Al1050 layers in the Al1050/AZ31/Al1050 laminated composites upon increasing the ARB cycle number, the KAM method, based on the intergranular misorientations estimation, was used. The KAM value is directly proportional to the dislocation density (Wang et al, 2022). In the present investigation, the KAM maps and the dislocation density measured by the EBSD technique are shown in Fig.…”

“…Kernel Average Misorientation (KAM) method in OIM™ software was used for the dislocation density assessment. KAM is known as the average misorientation angle of a given point with all its neighbors belonging to the same grain (Wang et al, 2022). In the present case, the θKAM value was calculated from the mean misorientation angle between a given point and its 3 rd neighbors excluding misorientations of 5°.…”
