Production of Al2O3–Ti2AlN composite with novel combination of high temperature properties

Al2O3–Ti2AlN composite with a high volume fraction (~40%) of Al2O3 was successfully fabricated by in situ solid reaction of nanoparticles produced by co-evaporation. The composite, characterized by small Al2O3 particles dispersed homogenously in a fine-grained Ti2AlN matrix, showed a novel combination of high temperature mechanical properties and oxidation resistance.
