Abstract

In this experimental research work Taguchi technique has been utilized for finding out the optimal parameter combinations that result for better ultimate tensile strength of hybrid Mg/(SiCp + Al2O3p + Grp) MMC. The process parameters that are used for the analysis are the furnace temperature (oC), stirring speed (rpm) and stirring time (min). Also considering significant process parameters mathematical models related to the ultimate tensile strength (MPa) has been established. An L27(313) orthogonal array has been utilized for finding out the optimum conditions. The optimal parametric combination where maximum ultimate tensile strength has been achieved are A3B2C3, respectively. The results of this investigation result in selecting suitable casting process parameters in fabricating hybrid Mg-MMC of desired strength and longer durability.
