Optimization of Process Parameters of Al-Si Alloy by Centrifugal Casting Technique Using Taguchi Design of Experiments

Abstract

In this paper, the influence of process parameters on the mechanical properties during centrifugal casting of aluminum alloy (4600) is studied. Taguchi method of design of experiments was employed to optimize the process parameters and to increase the mechanical properties. The investigation has indicated that increase in pouring temperature reduces mechanical properties while increase in die speed increases mechanical properties and density. Results were analyzed using ANOVA technique to know the percentage of contribution of each casting process parameters. Microstructures were studied under optical microscope and SEM were analyzed with process parameters by correlating with the mechanical properties of as cast structures.
