摘要
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.
