Abstract

A series of intermetallic matrix composites reinforced with Al2O3 based fibers were fabricated by pressure casting. The Al2O3 based fibers used were DuPont's 20 μm diameter Fiber FP and PRD-166 fiber, Mitsui's 10 μm diameter Almax fiber, and Saphikon's 125 μm diameter single crystal Al2O3 fiber. The intermetallic matrices employed were alloys based on Ni3Al, NiAl, Fe3Al, Ti3Al+TiAl, and Nb2Al+NbAl3. Optical, scanning and transmission electron microscopy were used to investigate the microstructure of the composites and the fibers. Tensile testing was conducted to determine the Weibull mean strength of the fibers in the as-received and heat treated conditions. The effect of fiber gage length on the Weibull mean strength of the PRD-166 and Fiber FP was evaluated. Indentation tests were performed to determine the effect of alloying additions on the fiber/matrix bond strength in shear in Saphikon fiber reinforced Ni3Al composites.
