QUANTITATIVE DETERMINATION OF THE TEXTURE OF Al-Li ALLOYS

P. Centre de Recherche et Developpement, B.P. This model enables t o take into account simultaneously the crystallographic texture, the morphology of grains, the

It is noted that the levels of tensile strength and yeild strength inprove as the recrystallization fraction increases and that the low slab reheating tqerature (400'~) with the

predicts a stress increment for the two alloys which is much smaller than the values actually observed[lO]. 4.1 CHEMICAL STRENGTHENING.--Of all the possible strengthening

Alloy samples were solution heat treated for 20 minutes at 540°C (580°C for 8090 into water; thermal analysis was undertaken immediately after quenching (AQ), after
