ABSTRACT Magnesium alloys have been increasingly used in the automotive and aircraft industry in recent years due to their Light weight Magnesium alloys have excellent specific strength and stiffness, exceptional dimensional stability, high damping capacity, and high recycle ability. Magnesium and its alloys are becoming widely recognized as playing an increasingly important role in automotive, aircraft, and electronic consumer products. Magnesium alloy metal matrix composite (MMC) containing 14 vol. % Saffil fibres. The squeeze casting process was used to produce the composites and the process variables evaluated were applied pressure, from 0.1 MPa to 120 MPa, and preform temperature from 250 °C to 750 °C
