Summary
Nextel™ 610 fiber-reinforced porous matrix composites with matrices containing various amounts of YAG and alumina were produced to determine the effect of YAG on retained tensile strengths after heating to 1100° and 1200°C. In all cases the YAG-containing composites gave higher ultimate stresses and greater strains to failure than the all-alumina composites when processed at 1200°C for times of up to 100 h. No correlation was found between strength and amount of YAG in the matrix; however, composites with matrices containing YAG, vs. alumina, as the binder phase had higher strengths. YAG was found to greatly hinder densification of alumina at 1200°C. The greater strengths of the YAG-containing composites can be attributed, at least in part, to a reduction in matrix densification, compared to the all-alumina matrix composite.
