Abstract

In hot rolled Ti-46.5at%Al-4at%(Cr,Nb,Ta,B) sheets a strong modified cube texture is found. The c-axes of the tetragonal unit cells in the grains are aligned with the transverse direction of the sheets. This texture causes an anisotropy of the creep resistance which is improved in transverse direction. Heat treatments with different subsequent cooling rates were performed in order to obtain lamellar microstructures with a different spacing of lamellae. Creep experiments exhibit an increase of the creep resistance which is highest after fast cooling. The texture measurements show no longer an alignment of c-axes after the heat treatment in the α-phase field, but a weak {110}-fiber texture in rolling direction occurs which causes a small improvement of the creep resistance in rolling direction. However, the creep resistance of the lamellar microstructure is more determined by the morphology than by the texture.
