Twenty vol% SiC reinforced-50/50 mol% MoSi2/WSi2 alloy matrix composites were fabricated by hot-pressing at 1900°C. Reinforcements examined were vapor-solid (VS) SiC whiskers, vapor-liquid-solid (VLS) SiC whiskers, and submicron SiC powders. All composites exhibited signficant plastic deformation at temperatures above 1200°C. Yield stress levels of alloy matrix composites were 8–10 times greater than those of pure MoSi2 at 1500°C, reaching values as high as 80 MPa at 1500°C.
