Abstract

The microstructure which results from the combination of production route and component choice is shown to influence the mechanical performance of a Nicalon reinforced aluminium-7%silicon-0.4%magnesium alloy. The microstructure is very complicated with silicon particles and iron-containing intermetallic phases in the matrix forming bridges between fibres. Formation of a spinel phase is observed at the Nicalon/matrix interface and also some suggestion of a magnesium-enriched zone. Mechanical performance of the composite is much poorer than expected and the reason for this is explained in terms of the microstructure.
