摘要: Abstract We report the microstructural characterization and compressive behavior of nanostructured Mg–10Al alloys processed via cryomilling, spark plasma sintering extrusion. demonstrate that warm extrusion leads to ~40% improvement in strength alloys. A yield 550 MPa, an ultimate 580 MPa are measured. The is mainly attributed occurrence precipitation hardening by γ-Al 12 Mg 17 nanoprecipitates basal-texture strengthening addition grain size mechanism. Our results suggest a successful approach for design high Mg–Al
