Development of crystallographic texture during processing of some aluminide based aerospace materials

Because of their lower specific weights, remarkably high strength and improved oxidation resistance, the aluminide-based intermetallic compounds are the candidates for substituting the rather heavy superalloys, at present used in compressors and turbines of aircraft engines. The ordered intermetallic compounds based on Ni3Al and Ti3Al have stimulated much interest due to their attractive and somewhat unusual properties. Thermomechanical processing constitutes an important route for forming these materials into suitable shapes for various applications. The processing route also influences the texture of the product, which in turn dictates the final properties. The present work summarises the evolution of textures during thermomechanical processing involving cold / hot rolling and subsequent annealing of a two phase Ni3Al base and a two phase Ti3Al base alloy.
