Abstract
A master alloy of the following composition: PA0 11 to 13% by weight tin, PA0 11 to 13% by weight zirconium, PA0 22 to 24% by weight molybdenum, PA0 22 to 24% by weight chromium, less than 0.5% by weight unavoidable impurities and balance aluminum is produced and utilized as a melting electrode in the vacuum-electric-arc production of titanium alloys to produce an alloy containing the elements of the master alloy in substantially the same weight relationships and with substantial freedom from oxides and nitride inclusions. The titanium alloys which result are particularly effective for aerospace use.
