Materials Analysis of Foreign Produced Flex Wings

Abstract

A material analysis was performed on two foreign produced flex wings. The steel alloy and fabrication sequence was identified. The mechanical properties of the steel as well as the corrosion resistance of the wing configuration researched. The flex wing was found to be fabricated from a martensitic Precipitation Hardening stainless steel (15-5 PM). The corrosion resistance (as judged from salt fog tests) was determined to be excellent. The wing halves were spot welded together after the 900 deg F age hardening heat treatment. The flex wing exhibited excellent spot weld quality and a fine martenistic microstructure. jg
