Effect of Rolling Orientation on the Mechanical Properties and Crystallographic Texture of 2195 Aluminum - Lithium Alloy

摘要

As-received sheets of 2195 aluminum-lithium alloy in the F temper of 3.18mm were cut at 0 deg, 45 deg, and 90 deg with respect to the rolling direction. The sheets were rolled at 24 percent reduction in thickness along these three directions after solution treatment and prior to aging. The alloy was solution treated at 507 deg C/30 minutes and aged at 143 deg 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.
