A Review on Manufacturing of Aluminium Alloy Based Metal Matrix Composites through Stir Casting Route

 A lot of research has been carried out over the past decades to develop an appropriate material that meets the rising demands of the industries. Aluminium is one of the most commonly used lightweight materials because of its corrosion resistance, soft ductility, and excellent electrical conductivity. However, aluminum is not efficient in high thermal loads due to its soft nature. Metal Matrix Composites (MMCs) are being built to address this drawback, which is a new class of engineering materials in which aluminum alloys are being used as a matrix. Hard ceramic particles (SiC, B4C, Al2O3 & ZrB2 ) are generally used as reinforcement phases. Such MMCs based on aluminum have enhanced mechanical properties such as high strength-to-weight ratio, better wear resistance, good fatigue resistance, and outstanding corrosion resistance, making them ideal for use in various fields such as marine, automotive, aerospace, and defense. Among different casting technologies, stir casting technology may be used because of its easy fabrication method and low manufacturing cost.
