Production and Characterisation of Aluminum-Titanium Di Boride Composite Using Powder Metallurgy Technique

In this project, a composite material containing Aluminum (Al), Titanium Di boride (TiB₂) are mechanically manufactured by method of powder metallurgy which will be effective in aerospace application. The composites will be tested by using different percentage composition of materials. The process will start by mixing Aluminum matrix with Titanium diboride reinforced with different percentage composition and the results will be compared with the values of pure Aluminum. The phase composition and morphology of material will be evaluated from hardness test. Metal matrix composites (MMCs) possess significantly improved properties including high specific strength; specific modulus, damping capacity and good wear resistance compared to unreinforced alloys. There has been an increasing interest in composites containing low density and low cost reinforcements. These composites are widely used in industries like aerospace, defense, automobiles, bio materials as well as sports etc. In present work aluminum alloy reinforced with TiB₂ MMCs materials are prepared by the powder metallurgical technique have cost advantage over the composites made by the other. Three different volume fractions (0%, 4%, and 8%) of particulate TiB₂ are used in the production of aluminum matrix composite at 680⁰ C. This feature is very likely and due to addition of Titanium diBoride (TiB₂) in Aluminum (Al) matrix, there will be a good interface bonding of uniformly dispersed submicron size of reinforced materials.
