Abstract: Process for shaping and improving the mechanical properties of blanks produced by powder metallurgy from an alloy with increased high-temperature strength by extrusion, and the deformation is successively performed in at least two temperature ranges different from one another or in two phases, in that the blank (2) is first reduced in its cross section at a temperature T.sub.1 and then is either agin reduced in at a lower temperature T.sub.2 or is deformed at a temperature T.sub.3 under counterpressure so that its cross section is further widened. T.sub.3 can be smaller than or equal to T.sub.1.

Abstract: Method for producing a heat-resistant aluminum-alloy workpiece having high transverse ductility which is manufactured from a compact produced by powder metallurgy, in which alloy powders are first cold-isostatically pressed under a pressure of 1500 to 5000 bar and the extrusion billet (2) produced in this manner is hot-recompacted and extruded to form a bar (7) with rectangular cross-section. Reduction ratio at least 6:1. A prismatic bar section (8) is separated from the bar (7) and is converted without further hot deformation and solely by machining into the final product in a manner such that the mechanical main load directions of the final product position themselves in a plane which is parallel to the plane which is extended through the extrusion direction and the longitudinal axis of the cross-section of the bar (7).
