Abstract
A masteralloy of the following composition: PA1 13 to 15% by weight tin, PA1 27 to 29% by weight zirconium, PA1 13 to 15% by weight molybdenum, PA1 up to 0.6% by weight silicon, 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.
