“…However, some contaminants, when present, can also have a deleterious effect on the interface. Of these, some attention has recently been devoted to Fe [9] , which is thought to segregate towards the interface in the form of the fragile compound Fe Al 3.…”

Rheocasting, as a semi-solid process, allows the production of aluminium matrix composites at relatively low temperatures (ca. 580ºC), thus favouring a reduced reactivity at the reinforcement-metal matrix interface. When one considers the possibility of further processing (such as any treatment involving remelting, even if partial) of the material, this trait allows a more rigorous control of the interfaces. Composite samples have been produced using as matrix an Al-7Si-0.3Mg alloy reinforced with SiC p (granulometry: 120 µm; V r = 0.30). These were rheocast at 583ºC, followed by compression and subsequent water-quenching. A structural characterisation (optical microscopy and XRD) of the as-received matrix material, as well as of the reinforced and non-reinforced rheocast material was performed. The phases identification will provide a basis for the understanding of the further processing where the rheocast material will be used as a precursor to produce functionally graded metal-matrix composites by centrifugal casting.

Carbon fiber reinforced aluminum alloy composites CF/Al composites are expected to be applied to electric power cable due to superior specific strength and specific modulus. But it is reported that CF/Al composites form aluminum carbide Al 4 C 3 at the interface between carbon fiber and aluminum alloy. However, influence of operating temperature, in usual 300°C, on the growth of Al 4 C 3 and tensile strength of CF/Al composites have not been clarified. In this study, at first, PAN-based CF M40J /Al composites are fabricated with ultrasonic infiltration method and hold at 300, 450, 500°C for 64 h. Secondary, influence of holding temperature on the quantity of Al 4 C 3 was investigated. Thirdly, relationship between the quantity of Al 4 C 3 and tensile strength of CF/Al composites was examined. As holding temperature increased, the quantity of Al 4 C 3 increased and tensile strength decreased. By examining extracted fiber with SEM, it was found that tensile strength should be decreased because Al 4 C 3 corroded carbon fiber. Kinetics calculation indicated that remaining strength of the CF/Al composites, held at 300°C for 36 years, was nought. As a result, it will be difficult to apply the CF/Al composites to electric power cable.
