Effect of rolling orientation on the mechanical properties and crystallographic texture of 2195 aluminum-lithium alloy

As-received sheets of 2195 aluminum-lithium alloy in the F temper of 3.18mm were cut at 0 degrees, 45 degrees, and 90 degrees with respect to the rolling direction. The sheets were rolled at 24% reduction in thickness along these three directions after solution treatment and prior to aging. The alloy was solution treated at 507 degrees C/30 minutes and aged at 143 degrees C/36 hours. The mechanical strength and anisotropy significantly increased. The crystallographic texture characteristics of as-received and rolled samples were determined and related to the changes in mechanical properties.
