SiC fiber-reinforced ZrTiO4 matrix composites were fabricated to study the effect of hot-pressing atmosphere (CO vs argon) on the mechanical properties and interfacial microstructure of the resultant composites. The effect of using CO heat-treated BN-coated Tyranno fibers as compared to untreated BN-coated Tyranno fibers was also investigated. Composites hot-pressed in CO with BN-coated Nicalon fibers resulted in a strong (960 MPa) and tough material. Composites hot-pressed with CO heat-treated BN-coated Tyranno fibers indicated that the microstructure of the heat-treated fibers was retained after processing. 14 refs.
