Investigation on Mechanical Properties of AA6061-TiC-Zro₂ Hybrid Composite using Taguchi Approach

Abstract Metal matrix composites (MMCs) are being used more frequently in the aerospace, automotive, and biomedical industries due to their low wear rate, high strength-to-weight ratio, etc. The Taguchi approach of design of experiments (DOE) was used to examine the MMC-derived AA6061. Taguchi approach. were used to determine which parameters will provide castings with the best possible tensile strength and hardness. Maintaining tight control over the processing parameters is crucial for producing defect-free castings. Modifications were made to the reinforcement percentage by weight (A), stirring rate (B), and processing temperature (C) before the test samples were prepared. Using an orthogonal array (OA) and analysis of variance (ANOVA), the impact of the process factors on the required attributes was investigated. The best parameters for improving the composites’ mechanical properties were found with the use of the Taguchi technique. The fundamental aim of this research is to establish the experimental parameters that, when combined with the desired hardness and UTS for specific uses, will provide defect-free composite casting. To demonstrate the efficiency of the Taguchi optimization method, a confirmation test was conducted using the optimum values for the processing parameters.
