Abstract

Sheets of 2195 aluminum-lithium alloy were solution-treated at 507 °C for 30 min. One set was stretched to 3-5% in the 0°, 45°, and 90° angle with respect to the original rolling direction. Two other sets were rolled 6% reduction in thickness and 24% reduction in thickness in the 0°, 45°, and 90° angle with respect to the original rolling direction. All specimens were aged at 143 °C for 36 h. A second group of samples was rolled at 24 and 50% reduction in thickness after a solution treatment of 507 °C for 1 h prior to aging at 190 °C for 24 h. Tensile specimens were machined from each sheet at 0°, 45°, and 90° angles to the original grain orientation. Tensile testing was used to determine the mechanical properties and anisotropic behavior of each condition. Rolling 6% reduction in thickness in the 45° orientation yielded anisotropy of 7.6% in the yield strength.
