  • Method of making reinforced intermetallic-matrix composites containing ceramics
    Patent number: 5679297
    Abstract: A method is described for making reinforced intermetallic matrix composites containing oxide ceramics. The method involves the oxidation of intermetallic powders under optimum conditions in an atmosphere containing oxygen, and the hot-pressed sintering process of oxidized intermetallic powders. The mechanical properties of intermetallic/oxide composites are superior to those of non-oxidized intermetallic sintered bodies.
