Development of Aluminium based metal matrix composites by stir casting method

Abstract

Aluminium 7050 is a predominant alloy that is used for various engineering applications such as aircraft, marine components. Metal matrix composite possesses improved characteristics such asstrength and hardness. Aluminium based MMC’s are receives attraction because of their exceptional characteristics. In this present investigation, an endeavour has been taken to develop aluminium-based (AA7050) metal matrix composite with Titanium dioxide(TiO2) as reinforcement. The composite is fabricated with the help of a stir casting process which exhibits better and improved properties than base materials.The composite is fabricated by varying the reinforcement (1–4%) weight combination. The fabricated composite is testedfor determining the mechanical properties as per ASTM standards. The tensile test and wear test have been performed on the fabricated metal matrix composite to identify the better mechanical properties.
