摘要	The mechanical properties, microstructures and fractures of a powder metallurgy Al alloy 6061-15vol.% SiC particle composite produced by extrusion were investigated. In order to build a basis for comparison, the composite was rolled at a warm temperature. The rolled composite after extrusion presents a much lower dislocation density than the extruded composite after T6 heat treatment. This cannot be explained by the difference between the coefficients of thermal expansion of aluminium alloy and SiC. In addition, the composite shows a non-uniform dislocation density and precipitate distribution so that matrix strength is non-uniform. A comparison of the properties between the rolled and unrolled composites indicates that the proper distribution of the matrix strength may be important to increase the ductility and toughness of the composite.
