Magnesium alloy based hybrid composites with varying levels of 8-alumina short fibers (Saffil_f®) and SiC particles (SiC_p) reinforcements have been prepared by the squeeze casting technique. Microstructure evaluation by optical microscopy and scanning electron microscopy on these composites reveal the presence of Mg₂Si and Al-RE precipitates. The presence of these precipitates was found to enhance the creep resistance of AE42 hybrid composites. The interfacial reaction products were MgO and Mg₂Si. The interfacial reaction product MgO is more pronounced along the Saffil_f® compared to SiC_p . Heat treatment of the composites improved the distribution of the precipitates in the composites. Hardness characteristics of the composites have been studied.
