Abstract
Abstract The preparation of an Al–3·8Fe–3·6Ni–3·8Co engineering material from atomized powders is described. The production route involves cold compaction followed by extrusion at 400–600°C. It is shown that products having acceptable surface finishes may be produced and that the properties of the products are related to the extrusion parameters. The structure is considerably modified during the deformation processing and is much coarser than that existing in the individual powder particles. The properties of the product are superior at room temperature to those of existing non-heat treatable Al alloys and the material maintains its considerable strength at elevated temperatures. PM/0284
