Abstract In this study, Al-Si compacts and Al-Si/B 4 C composites were produced from
hypereutectic Al-Si alloy powders by cold pressing/conventional sintering and cold
pressing/microwave sintering techniques. The effects of sintering temperature, sintering time
and B 4 C particle addition on microstructural properties, density, hardness and transverse
rupture strength were investigated. The phases and intermetallic compounds formed in the
microstructure were determined by X-ray diffraction. Densities of the samples were …
