摘要

Fiber reinforced titanium matrix composite is considered as a superior material for advanced lightweight aerospace application. Fiber/matrix interfacial reaction has a significant effect on the mechanical properties of the composites. The SCS-6 SiC fiber reinforced Ti-6Al-4V matrix composite was prepared by foil-fiber-foil (FFF) method at ONERA, France. Stripe samples were cut from the as-consolidated composites and sealed in silicon carbide tube. One group of the samples were annealed for 58h at 550°C, 700°C, 850°C and 1000°C, the other group were annealed at 1000°C for 43 h, 58 h, 80 h, l00 h, respectively. The interface investigation indicated that the connection between SiC fiber and the matrix is favorite in the composite. And the interface width for as-consolidated composite is only about 0.8 μm. The interface width increase with the prolong of annealing time and the increase of annealing temperature. But the increment for the latter is not as high as the former one, which means the annealing time may be the prior factor to influence the interface reaction. The interface width for the composite annealed at 1000°C for l00 h is about 20 μm. Interface composition of the composite detected by EDX is as follows: Ti 87.58 wt%, V 4.91 wt%, Al 4.06wt%, Si 3.45 wt%.
