Interface reaction between CVD-SiC fibers and molten aluminum alloys

Abstract

Interface reactions between the fibers and the matrix have been investigated on the CVD-SiC fiber reinforced aluminum and Al-Si alloys. The cross sectional area of the reaction zone around the type SCS-6 SiC fiber was larger than that around the type SCS-2 SiC fiber. The amount of reaction products around SiC fiber depends not only on the silicon content in the matrix but also on the type of fiber, and it is larger around the type SCS-2 SiC fiber than around the SCS-6 SiC fiber, in correspondence with the differences in the carbon rich layers.
