Investigation of Mechanical Properties on Newly Formulated Hybrid Composite Aluminium 8011 Reinforced With B4C and Al2O3 by Stir Casting Method

Metal matrix composite (MMC) focuses primarily on improved specific strength, high temperature and wear resistance application. From the collected literature it is found that, metal matrix composite are under serious consideration as potential candidate materials and it is mainly used to replace conventional materials in aerospace and automotive applications. So, the MMC are highly used in automotive and space applications. And the aluminium matrix composite is a material with two constituent parts, one being a metal and other being reinforcement. The aluminium matrix can be strengthened by reinforcing with hard ceramic particles like SiC, Al2O3, B4C etc. In this project, Aluminium 8011 alloy is chosen as one of constituent parts, which has good mechanical properties and exhibits good weldability. The mechanical properties like tensile strength, compression strength and hardness can be increased by reinforcing Al 8011 matrix with boron carbide (B4C) and aluminium oxide (Al2O3) particles. In this project, the fabrication of aluminium 8011 with boron carbide and aluminium oxide is done by stir casting process, which is a liquid state material fabrication and cost effective method. Characterization test were conducted on Aluminium 8011 alloy to study the change in tensile, compression and hardness properties of alloy.
