MECHANICAL PROPERTIES EVALUATION OF TIB2 & NB REINFORCED ALUMINIUM 7075 FOR PUMP IMPELLER APPLICATIONS

Aluminum composites were largely used in automobiles industries due to their light weight and corrosion free characteristics. Mechanical properties of Aluminum alloy were improved by the reinforced of TiB2. The composites were fabricated by three varying the volume percentage of TiB2 particles and Niobium. The three material matrix composites can be manufactured by stair casting method. These composites were evaluated for microstructure and mechanical property by FEA.The test results shows that overall mechanical properties of different composite samples were better than bare metal.
