This study demonstrates that introducing multidimensional crystallographic defects through severe plastic deformation may overcome the strength-ductility trade-off in magnesium alloys. We developed a unique hyper-substructure (HSS) microstructure via novel upsetting-assisted asymmetric extrusion at low temperature (∼220 °C). The UE-55 specimen with ∼0.34 upsetting strain exhibited exceptional properties: ∼266.5 MPa yield strength, ∼311.9 MPa ultimate tensile strength, and ∼27.6% fracture elongation in a low-alloyed magnesium system (∼3.3 wt.% total alloy content). Remarkably, HSS simultaneously enhances both strength and ductility. Refined grains and elevated dislocation density within HSS primarily strengthen the material. Enhanced plasticity stems from synergistic mechanisms. Pre-existing dislocations multiply during tension through interaction-mediated processes, facilitating c-axis deformation. Simultaneously, linearly aligned low-angle boundaries (LABs) obstruct the propagation of microcracks initiated near high-angle boundaries (HABs) by fractured coarse secondary phases. This significantly improves the material’s microcrack accommodation capacity. This work establishes substructures as primary carriers of plastic deformation, diverging from conventional rapid extrusion techniques that produce fully recrystallized microstructures. The resultant strength-ductility synergy emerges from coordinated strengthening mechanisms. Notably, processing at 20.6 m/min extrusion speed enables efficient fabrication of high-performance magnesium extrudates. Furthermore, analysis of HSS formation mechanisms provides novel insights for industrial-scale production of cost-effective magnesium alloys.

Ultrathin metallic foils deform under plane-stress conditions, where the absence of through-thickness constraint and a low thickness-to-grain-size ratio (t/d) promote early necking and severely limit uniform elongation. Here, we demonstrate that high-ratio differential speed rolling (HRDSR) mitigates these geometric limitations in Mg–10Li alloy foils by refining grains to the nearly ultrafine regime, thereby increasing t/d and activating grain-boundary–mediated deformation. Foils 100 μm thick with grain sizes of 1.1 μm (t/d ≈ 91) exhibit elongations exceeding 30 % at 10−5 s−1, whereas coarse-grained counterparts (29.4 μm, t/d ≈ 3.4) of the same thickness fail abruptly with < 1 % uniform strain under identical conditions. Micro-pattern formability tests confirm homogeneous deformation and high surface fidelity in ultrafine-grained foils, in sharp contrast to severe strain localization and pattern collapse in coarse-grained samples. Strain-rate jump tests on the ultrafine-grained foils reveal an elevated strain-rate sensitivity (m ≈ 0.23) and low activation volumes (15–30 b3) at low strain-rates, suggesting that deformation is governed by a combined contribution of grain boundary sliding (GBS) and dislocation climb creep (DCC). A unified constitutive framework captures the transition from DCC at moderate strain-rates to GBS at low rates. The present findings demonstrate that refining Mg–Li alloys to a quasi-ultrafine-grained regime effectively overcomes the intrinsic ductility limitations imposed by plane-stress geometry, thereby enabling their practical application in flexible electronics, bioresorbable implants, and lightweight energy-storage systems.
