7XXX series aluminum alloys (Al 7XXX alloys) are widely used in bearing components, such as aircraft frame, spars and stringers, for their high specific strength, high specific stiffness, high toughness, excellent processing, and welding performance. One of the most commonly used aluminium alloy for structural applications is Al7075 alloy due to its attractive comprehensive properties such as low density, high strength, ductility, toughness and resistance to fatigue. Another important alloy in the Al 7XXX series is Al7178. It has exceptional uses in Aviation field, Automobile sector, and Structural industries. In the present research work an attempt is made to prepare a blend of these two alloys and get the optimum composition which yields high strength Al 7(075+178). A medium frequency induction furnace with graphite crucible was used for the melting. Mechanical properties like Tensile strength and Hardness are selected as the output response along with the Microstructural analysis. Taguchi method was adopted for designing experimental composition of the composite which is prepared.

Abstract


7XXX series aluminum alloys (Al 7XXX alloys) are widely used in bearing components, such as aircraft frame, spars and stringers, for their high specific strength, high specific stiffness, high toughness, excellent processing, and welding performance. One of the most commonly used aluminium alloy for structural applications is Al7075 alloy due to its attractive comprehensive properties such as low density, high strength, ductility, toughness and resistance to fatigue. Another important alloy in the Al 7XXX series is Al7178. It has exceptional uses in Aviation field, Automobile sector, and Structural industries. In the present research work an attempt is made to prepare a blend of these two alloys and get the optimum composition which yields high strength Al 7(075+178). A medium frequency induction furnace with graphite crucible was used for the melting. Mechanical properties like Tensile strength and Hardness are selected as the output response along with the Microstructural analysis. Taguchi method was adopted for designing experimental composition of the composite which is prepared.
