Abstract
Metallic matrix composites include a high strength titanium aluminide alloy matrix and an in situ formed aluminum oxide reinforcement. The atomic percentage of aluminum in the titanium aluminide alloy matrix can vary from 40% to 48%. Included are methods of making the metallic matrix composites, in particular, through the performance of an exothermic chemical reaction. The metallic matrix composites can exhibit low porosity.
