Abstract: | The viability of developing an SiC fibre-reinforced titanium/titanium aluminide hybrid matrix composite was explored. The
hybrid composites are expected to be used at temperatures beyond those attainable in conventional titanium matrix composites
while improving the damage tolerance of the titanium aluminide matrix composites. The room-temperature mechanical characteristics
studied were tensile strength, fracture toughness, low-cycle fatigue life and fatigue crack growth rate. The mechanisms of
damage initiation and propagation under various loading conditions were also characterized. The directions for developing
a satisfactory composite with hybrid titanium/titanium aluminide matrix are also addressed. |
