Abstract

Non-ferrous materials are widely used in industries, especially because of its corrosion resistance property. Among them aluminium alloys are widely used because of its ease of machinability, good thermal Conductivity, less weight etc. Presently Aluminum is more used by industries than steel. Further aluminium with alloy elements like copper, nickel, magnesium, tin etc. will enhance the properties of the materials and these alloyed elements have more industrial applications. Solution Treatment enhances the properties of these aluminium alloys. This work is focused on synthesis and characterization of hexenary aluminium alloy (Al-Cu-Sn-Ni–Mg-Fe) by gravity die casting technique. The microstructure and wear behavior of as cast, solution treated alloys were elucidated by optical microscopy, pin-on-disc wear test. The mechanical properties were assessed by the tensile test, hardness test and compressive test. Solution treated aluminium alloy showed the remarkable improvement in wear resistance, hardness and tensile strength. The uniformly dispersed thermally stable ? and O phases in the aluminium matrix are one of the predominant factor in improving the hardness and tensile properties. The increase in hardness was achieved with solution treatment significantly reduced the wear rate.
