OSTI ID:10182584
Ductile nickel-aluminide intermetallic alloys have been successfully used to toughen ceramic materials intended for use at a wide range of temperatures. Traditional ceramic processing procedures have been used to produce a variety of microstructures. The fracture toughness increases with increasing particle aspect ratio, however, the flexural strength decreases with increasing particle size. Fracture toughnesses up to 7.6 MPa m{sup 1/2} and flexural strengths up to 550 MPa were observed in an alumina composite containing 10 vol.% nickel aluminide.
