Optimization of Casting Parameters on Al/RHA Composite Using Taguchi Method

Abstract:

In the present work, Taguchi method was employed to optimize tensile strength and hardness of the stir casted Al/RHA composite. The composites were prepared by varying stir casting parameters like stirring time (6, 9, 12 min), stirring speed (100,200,300 r.pm), and weight percentage of RHA reinforcement (6, 9, 12 %). All the experiments were conducted based on plan of experiments (L₉ Orthogonal array) generated through Taguchi Technique. The individual influence of each process parameters on the hardness and tensile strength was determined by using analysis of variance. The result implies that the wt. % of RHA reinforcement was found to be a highly influenced parameter followed by stirring time and stirring speed. Finally, confirmation test was done to verify predictive model with the experimental results.
