Abstract Microstructures of Si-Ti-C-O fibre-reinforced aluminium and aluminium alloys were investigated by scanning electron microscopy, and both conventional and analytical transmission electron microscopy. In the latter samples, some inclusions were observed between the matrix and the fibres. From the electron diffraction, high resolution microscopy and compositional analysis by energy-dispersive X-ray, the inclusions were identified as the α-Al-Si-Fe phase. Since the longitudinal three-point bending strength decreases with the increase of iron content, it was concluded that the α-phase inclusions on the surface of the fibre contribute to the lower strength of the composites based on this alloy.
