Abstract

Process is for avoiding material defects in metals and alloys, esp. in Ti and its alloys, which are melted under reduced pressure in a sealed furnace using an arc, electron-beam, or other suitable sources of energy, and where part of the substances in the melt or in added materials enters the gaseous phase. The substances in the gas phase, which condense to the solid state under the temp. and pressure used in the furnace, are deposited on a condens. device located in the furnace. The condensn. device is pref. cooled to the lowest temp. inside the furnace. The condensn. device is pref. cooled to the lowest temp. inside the furnace, and the pref. device is a cooling finger or ring located very near to the melt. Prevents condensed volatile matter from re-entering the melt. Prevents e.g. segregation in ti alloys producting high interstitial defects or beta-flecks and, where two re-melting procedures are normally required, one can be eliminated.
