Al-Zn-Mg/SiCPcomposites processed by a liquid metal processing (stir casting) technique have been microstructurally characterised in the as-cast and extruded conditions. Uniform distribution of SiCPis observed with few defects, such as particle clusters, which are due to partial wetting and associated gas porosity. The constituent particles are associated with SiCPalthough their composition remains unaffected compared with the control alloy. Hot extrusion of the composite using a shear type die showed banding of particles in the extruded direction with 9 vol. % composite. Such defects however, are not predominant in 18% SiCPextruded composites. The presence of Mg2Si is detected at the particle matrix interface as well as in the matrix. |
