摘要：

We have used severe plastic deformation (high-pressure torsion straining) to achieve cold consolidation of gas-atomised Al90Fe5Nd5 powders into bulk nanostructured disks with a dispersion of fcc-aluminium crystallites within the glassy matrix with full density and hardness in excess of 3 GPa. The micro- and nanostructure of the resulting disks is presented. (C) 2002 Published by Elsevier Science Ltd. on behalf of Acta Materialia Inc.
