VERFAHREN UND VORRICHTUNG ZUR HERSTELLUNG VON METALLISCHEN LEGIERUNGEN FÜR VORMATERIALIEN, BAUTEILE, WERKSTÜCKE ODER DERGLEICHEN AUS TITAN-ALUMINIUM-BASISLEGIERUNGEN

摘要

The invention is directed to a Titanium-aluminum base alloy articles are produced from pieces of starting materials by melting thereof in a metallic melting crucible having a rotating electrode or a plasma- or electron beam device and there is then accomplished arc remelting, preferably vacuum-arc remelting following the melting of the pieces of starting materials. Furthermore, the arrangement for the manufacture of the articles formed of titanium-aluminum base alloys comprises a melting apparatus containing a rotating electrode or a plasma- or electron beam device and a vacuum-arc melting apparatus.
