Method of making reinforced intermetallic-matrix composites containing ceramics

摘要

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.
