EVALUATION OF LARGE TITANIUM ALLOY FORGINGS

Abstract

The purpose of this program is to evaluate large titanium forgings for reliable use in advanced weapon systems. Four forgings of Ti-6Al-4V and four forgings of IMI679 will be used in the evaluation. Two forgings of each alloy will be machined into test coupons for material property tests, one forging will be full scale fatigue tested and the other forging will be full scale static tested. All forgings have been produced and heat treated. Machining of two forgings each of Ti-6Al-4V and IMI679 to a modified F-104 aft fuselage ring fitting is nearly completed. Preparation of material property test coupons removed from the forgings of IMI679 was started and some testing completed. Preliminary smooth tension, notched tension, compression and fatigue data on IMI679 are presented. (Author)
