Zusammenfassung:A powder metallurgy method includes a canister that has canister walls that define a hermetic chamber that circumscribes an open central region. A metallic alloy powder is inserted into the hermetic chamber, followed by evacuating the hermetic chamber. The canister with the metallic alloy powder is then subjected to a hot isostatic pressing process that includes heating the canister and the metallic alloy powder and applying isostatic pressure to the canister. The heating and the isostatic pressure causes fusion and consolidation of the metallic alloy powder to form a solid workpiece. The canister is then removed from the solid workpiece
