Abstract

The processing of Al/TiO2 composite powders produced by high-energy mechanical milling leads to production of a range of valuable, titanium-based materials. They include Ti(Al,O)/Al2O3 and TixAly(O)/Al2O3 composite powders, bulk composites and Ti3Al/TiAl alloy powders, and corresponding bulk materials. The strength of the Ti(Al,O)/Al2O3 and TixAly(O)/Al2O3 composites is moderate, but their high-temperature oxidation resistance is exceptionally high, making the titanium-based composite powders favorable feedstock materials for protective coatings. The hardness of the Ti(Al,O)/Al2O3 and Ti3Al(O)/Al2O3 composites is also very high (10–16 GPa).
