Role of shear strain in ultragrain refinement by accumulative roll-bonding (ARB) process

The role of shear strain on ultragrain refinement. of aluminum during accumulative roll-bonding (ARB) process was studied. The complicated distribution of redundant shear strain through thickness of the ARB processed sheets was quantitatively shown first, and good correspondence between the grain size and the amount of shear strain was found.
