OPTIMIZATION OF LANTHANUM OXIDE (LA2O3), ALUMINIUM OXIDE (AL2O3) INCORPORATED ALUMINIUM METAL MATRIX COMPOSITES DEVELOPED USING STIR CASTING MACHINE
Original language description
As lightweight materials with enhanced mechanical and tribological properties, aluminum metal matrix composites, or AMMCs, are attracting more and more attention. This work used the stir-casting process to reinforce Al 6063 alloy with rare earth oxide (LaO3) and alumina (AlO3) to create a hybrid AMMC. A consistent distribution of reinforcements inside the matrix was verified by SEM and EDS investigation. The composite's machinability was further examined using electro discharge machining (EDM), in which the rate of material removal (MRR) and wear rate of the cutting tool (TWR) were maximized by optimizing the input parameters of current, trigger on (Ton), and trigger off (Toff). Box-Behnken Design (BBD) was used to arrange the experimental trials, and mean effect and signal-tonoise ratio (S/N) diagrams were used to assess the data. Subjective weight allocation techniques were combined with multi-criteria decision-making (MCDM) techniques, specifically MABAC and MOORA, to attain a balanced trade-off between MRR and TWR. 9 A current, Ton of 5, and Toff of 4 were found to be the ideal parameter settings, guaranteeing increased machining efficiency with no tool deterioration. The results demonstrate the potential of hybrid AMMCs supplemented with rare earth elements in applications that demand enhanced machinability and structural dependability.
