RESEARCH AND DEVELOPMENT IN HIGH STRENGTH HEAT RESISTANT ALLOYS

Abstract

THE SCALE-UP OF SEVERAL Ta and W base alloys to a 2-in.-diam ingo size by arc melting was accomplished. A 2500 ampere A-C power supply has been installed for consumable electrode melting of W-base materials and extensive arc furnace modifications have been made. A comparison is included between A-C and D-C melting for primary consolidation of Ta and W alloys. Studies are underway to determine the best methods for machining, grinding and cutting W and Ta alloy shapes which must be conditioned. A technique of intermediate screening of promising alloys is now being utilized. This consists of producing arccast sheet bar shape in a button melting furnace for subsequent direct conversion to strip by hot rolling. Some hot-hardness data have been obtained at 2000 F on several Ta base alloys. (Author)
