  Al/Ni multilayers have been prepared by repeated folding and cold rolling
(F&R) of elemental foils. The thickness of Al and Ni foils is reduced down to
less than 50 nm after fifty F&R cycles. Three-dimensional atom probe analyses
clearly reveal the presence of supersaturated solid solutions and give the
evidence of deformation-induced intermixing. The formation of the solid
solutions and their transformation into the Al3Ni phase upon annealing is
discussed.
