Evaluation of 2090-T8E48 Aluminum-Lithium Plates
Abstract
A 1.5-inch-thick 2090-T8E48 aluminum-lithium (Al-Li) alloy plate was evaluated in conjunction with the Navy Cooperative Test Program. Mechanical characterization included testing of tensile specimens in the longitudinal, transverse, and short direction, and testing of compact tension/slow bend specimens covering the L-T, T-L, L-S, S-L, S-T, and T-S directions. In addition, ballistic tolerance against caliber .30 armor piercing projectile and 20-mm fragment simulated projectile was determined. Corrosion and stress corrosion studies were made in accordance with ASTM standards. Microstructural characterization was performed through optical metallography and transmission electron microscopy. Consolidation and discussion of all the results in comparison with previously evaluated 0.5-inch-thick X2090-T8 is presented.
