AbstractThe nanocrystalline (nc) microstructure was studied in a surface layer of an Al alloy induced by the surface mechanical attrition treatment, nc grains with the larger-end of the nanometer size regime (∼50-100 nm) formed through continuous refinement via grain subdivision mechanism, in a sequence of deformation bands with elongated subgrains, submicro-, and nc-grains leveling off ∼46 nm. Meanwhile, nc grains with the lower-end of the nanometer size regime (∼<10 nm) were observed to occur at a critical strain. A dynamic recrystallizatiou mechanism was suggested to account for their formation.
