The texture and anisotropy of as-rolled and rolled and annealed Ti-22Al-23Nb foil have been investigated. The texture of the b.c.c. phase was analyzed and used to calculate the anisotropy of the foil. The predicted variation in yield stress is in good agreement with the experimental results. The texture of the b.c.c, phase is similar to textures observed in conventional b.c.c. alloys. The texture of the orthorhombic and hexagonal phases has also been analyzed. Although limited data exist for the single crystal properties of the alpha phase, prediction of the anisotropy of the orthorhombic phase is hindered by the absence of such data. The results to date indicate that the texture of the cubic phase predicts the anisotropy of the intermetallic foil reasonably well. Theoretical analysis of the single crystal yield surface of the orthorhombic phase shows that a deformation mode map can be constructed for this material. Comparison of simulated with experimental textures suggest limits on the variation of critical resolved sheer stress among the four different slip systems. Elsevier Science S.A. All rights reserved.
