TUNGSTEN FORGING DEVELOPMENT PROGRAM

Abstract

The commercial forging process developed for complex structural W-15%Mo forgings was verified through a production run resulting in an exceptionally high yield of sound universal forgings. Of 32 sound starting billets, 31 were forged successfully through the 3-step sequence utilizing conventional heating and forging equipment. Precision tolerances of + or - 0.015 in. for length, width, and thickness were maintained throughout the production run with only 1 set of commercial die steel tooling for each operation in the sequence. Ductile/brittle transition tests demonstrated the low longitudinal and transverse transition temperatures achieved in the W-15%Mo forged by the process. Stress rupture and creep properties for e forged material at 3000, 3250, 3500, and 3750 F are also reported. (Author)
