Synthesis and Characterization of AL–SiC–B4C Hybrid Metal Matrix Composite

In this study, the fabrication of Al-6061 + 10% wt. SiC + 10% wt. B4C and Al-7075 + 10% wt. SiC + 10% wt. The stir casting process does B4C hybrid MMC. The mechanical properties like tensile strength, maximum tensile strength and hardness are determined. EDM machining has been applied to both these fabricated specimens to obtain high product quality and improved performance levels. The copper electrodes have been used for EDM machining. Taguchi technique is implemented to framework the layout of the experiment. Current, voltage and pulse on time are taken as machining parameters, whereas MRR and surface roughness value are response or machining evaluation parameters. Anova optimization technique is implemented to determine the relative effect of machining parameters on the response parameters and also to determine the percentage contribution of all the factors of the selected machining parameters for MRR and surface roughness.
