Abstract
The alloy Ti-24Al-11Nb was hot rolled in the β phase field at 1523 K by 80% and water quenched. The material was then aged at 773 K, 873 K and 1173 K for various lengths of time leading to the formation of the O phase and the α2 phase, either directly from the β or via β to O phase transformation. The O phase shows a “tweed” microstructure while the transformed α2 phase displays the typical plate like features. The texture of the α2 phase whether formed directly or indirectly from the β phase, due to a final ageing treatment at 1173 K, is rather strong and non-basal type. By contrast, the α2 texture of the 873 K aged material is weak and again non-basal type, but it differs significantly from the texture of the 1173 K aged material.
