Abstract

Aluminium Metal Matrix Composites (MMC) is beneficial in a diversity of applications of engineering, particularly due to their strength while being lightweight. The intention of this paper is to develop a Hybrid Metal Matrix Composite (HMMC) using base metal aluminium alloy which is reinforced with different wt% of Graphite and Titanium Dioxide and then study the different mechanical properties like microstructure analysis, tensile strength, hardness, and wear behavior of HMMC developed experimentally. We need to calculate how much base metal and reinforcements material is required. Stir casting is used for producing new hybrid composite material in the present investigation. Preheating of reinforcement materials needs to be done before doing the casting. After fabricating the hybrid composites, Specimens for the various tests were prepared as per ASTM Standards. Microstructure analysis, tensile test, hardness, and wear tests were performed for the base metal as well as the four combinations of second phase particle composites. We achieved ultimate tensile strength about 123.3 N/mm2 and hardness value of 103.3. BHN for the combination LM12+6% Gr+ 6% TiO2 of was obtained due to proper stirring process and mixing of the reinforcement material with base metal. It was observed that with same combination the wear rate goes on varying with load and speed, wear rate decreases up to almost 30 to 40% compared with only base metal.

Keywords: Aluminium alloy, Composite, Titanium Dioxide, Microstructure, Tensile strength, Hardness
