Al-7.5Mg powders were cryomilled, then consolidated and extruded to produce bulk nanostructured material. The extrusions had a tensile yield strength of 641 MPa and an ultimate strength of 847 MPa. Additional samples were prepared by combining cryomilled powder unmilled Al-7.5Mg, resulting in extrusions with high strength and increased ductility. (C) 2003 Acta Materialia Inc.
