Abstract
Materials that are difficult to cast and work may be prepared by using powder extrusion as a primary fabricating technique. The Al-Fe system was selected for study and is examined in detail. The effect of varying the extrusion conditions on the structure and substructure development and on the mechanical properties of the final product is investigated. It is shown that the mechanism of extrusion provides an explanation for the various properties observed, and that for this alloy the oxide content is not significantly property-controlling.
