Abstract
A masteralloy of the following composition: PA1 10 to 12% by weight tin, PA1 21 to 23% by weight zirconium, PA1 32 to 34% by weight molybdenum, 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 masteralloy 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.
