The work provides evidence that the heterogeneous grain refinement pathway in a dispersion-strengthened Al alloy tends to reach a saturation limit under severe plastic deformation, rather than continuing indefinitely. By extending ECAP processing to a cumulative strain of e = 16, the study demonstrates that nanoscale dispersoids present in the alloy not only catalyze grain refinement by promoting strain localization, but also ultimately define its limit by pinning the dislocations and resulting boundaries - thus establishing a steady-state ultrafine-grained structure.
