Aluminium alloy (7178) of die casting involves process parameters like weight percentage of Zn, Mg, Cu, Cr Si. Fe, Mn and Ti etc. with this Zn, Mg, Cu and Cr are selected as process parameters and other parameters are kept constant. Experiments were conducted Taguchi’s L-9 orthogonal array. Castings were made under the various parameter at three different level. In this investigation, the effect of process parameters on mechanical properties of castings of aluminium alloy (7178) is studied. Taguchi method design of experiments employed to optimize the parameters of process that leads maximum mechanical properties. The investigation has indicated that influence of parameters like Zinc (Zn), copper (Cu) magnesium(Mg) and chromium (Cr) on properties of mechanical like Tensile strength, Hardness and microstructure analysis. Results were analysed by ANOVA Technique. Microstructures were studied under optical microscope. The optimal parameters of process for castings of aluminium alloy for better mechanical properties have been determined.

Abstract


Aluminium alloy (7178) of die casting involves process parameters like weight percentage of Zn, Mg, Cu, Cr Si. Fe, Mn and Ti etc. with this Zn, Mg, Cu and Cr are selected as process parameters and other parameters are kept constant. Experiments were conducted Taguchi’s L-9 orthogonal array. Castings were made under the various parameter at three different level. In this investigation, the effect of process parameters on mechanical properties of castings of aluminium alloy (7178) is studied. Taguchi method design of experiments employed to optimize the parameters of process that leads maximum mechanical properties. The investigation has indicated that influence of parameters like Zinc (Zn), copper (Cu) magnesium(Mg) and chromium (Cr) on properties of mechanical like Tensile strength, Hardness and microstructure analysis. Results were analysed by ANOVA Technique. Microstructures were studied under optical microscope. The optimal parameters of process for castings of aluminium alloy for better mechanical properties have been determined.
