Abstract
The measurement of misorientation angle distributions following different amounts of deformation in cold-rolled aluminum and nickel and compressed stainless steel is reported. The scaling of the dislocation cell boundary misorientation angle distributions is studied. Surprisingly, the distributions for the small to large strain regimes for aluminum, 304L stainless steel, nickel, and copper (taken from the literature) appear to be identical. Hence the distributions may be “universal.” These results have significant implications for the development of dislocation based deformation models.
