A study of the in-plane anisotropy in the fracture toughness of Al-Li 8090 alloy in the L-T, L+45 degrees, and T-L orientations was conducted. It was found that the anisotropy arises because of the variation in the work hardening exponent, yield strength and interparticle spacing of precipitates with different notch orientation. The crystallographic texture is responsible for the variation in yield strength and work hardening coefficient, whereas the highly uncrystallized ...
