Patent number: 7870670Abstract: The invention proposes a process for producing components (10) or semi-finished products which contain intermetallic titanium aluminide alloys, which includes the following process steps: rough contouring of a plurality of plate-like bodies (11) so as to correspond to a desired final shape of the component (10) or semi-finished product, some of these plate-like bodies or all the plate-like bodies consisting of titanium aluminide alloys; carrying out surface-to-surface joins between the plurality of plate-like bodies (11) stacked on top of one another so as to form an overall body (10); and forming the desired final shape of the overall body (10). The invention also concerns a component, in particular for jet engines, which is produced using this process.Type: GrantFiled: February 24, 2005Date of Patent: January 18, 2011Assignee: GKSS-Forschungszentrum Geesthacht GmbHInventors: Michael Oehring, Jonathan Paul, Fritz Appel

Publication number: 20100119402Abstract: In an alloy based on titanium aluminides, metal droplets are obtained from a titanium aluminide metal melt. The metal droplets are enriched with halogens resulting in halogen-enriched titanium aluminide metal droplets. The alloy is molded from the halogen-enriched titanium aluminide metal droplets by, preferably hot isostatic, pressing. Titanium aluminide powder can be heated in a container, for a predetermined period of time, wherein an atmosphere, enriched with halogens, is or will be provided in the container, so that a halogen-enriched titanium aluminide metal powder is formed, or metal droplets are formed from a titanium aluminide metal melt. The metal droplets are enriched with halogens so that halogen-enriched titanium aluminide metal droplets result. Subsequently, the alloy is molded from the halogen-enriched titanium aluminide metal droplets.Type: ApplicationFiled: January 8, 2010Publication date: May 13, 2010Applicant: GKSS-FORSCHUNGSZENTRUM GEESTHACHT GMBHInventors: Jonathan PAUL, Fritz APPEL, Michael OEHRING

Patent number: 7115177Abstract: In a method for the treatment of metallic materials especially for the consolidation of the texture of the materials, a blank of the metallic material is heated to a transformation temperature and the blank is then subjected to twisting preferably while, at the same time, being compressed. In this way, the texture can be refined to a large degree in a simple and inexpensive manner.Type: GrantFiled: December 11, 2001Date of Patent: October 3, 2006Assignee: Gkss-Forschungszentrum Geesthacht GmbHInventors: Fritz Appel, Stephen Eggert, Uwe Lorenz, Michael Oehring
