A three-level heterogeneous grain structure with grain sizes spanning the nanometer to micrometer range, imparting a high yield strength well in excess of 1 GPa leads to a sustainable strain hardening rate, a record-wide hysteresis loop in load−unload−reload stress−strain curve and hence high back stresses.

A thermomechanical treatment of Cu is described that results in a bimodal grain size distribution, with micrometre-sized grains embedded inside a matrix of nanocrystalline and ultrafine (<300 nm) grains, which impart high strength, as expected from an extrapolation of the Hall–Petch relationship.

It is reported that the gradient structure in engineering materials such as metals renders a unique extra strain hardening, which leads to high ductility, which is a hitherto unknown strategy to develop strong and ductile materials by architecting heterogeneous nanostructures.
