    • The invention relates to a process for producing an alloy based on titanium aluminides. Here, metal droplets are obtained from a titanium aluminide metal melt, in particular using the gas atomization process, the metal droplets are enriched with halogens by exposure to a halogen-containing gas so that halogen-enriched titanium aluminide metal droplets are obtained and the alloy is subsequently formed from the halogen-enriched titanium aluminide metal droplets by pressing, preferably hot isostatic pressing. In further embodiments of the process, pulverulent titanium aluminide, in particular titanium aluminide metal powder, is heated in a, preferably closed, vessel for a predetermined time, where a halogen-enriched atmosphere has been or is provided in the vessel so that halogen-enriched titanium aluminide metal powder is formed during the heating time, or metal droplets are obtained from a titanium aluminide metal melt, in particular using the gas atomization process, the metal droplets are enriched with halogens by exposure to a halogen-containing gas so that halogen-enriched titanium aluminide metal droplets are formed, with the alloy being subsequently formed in each case from the halogen-enriched titanium aluminide metal droplets by pressing, preferably hot isostatic pressing.
