| dc.description.abstract | In developing countries, the importation of synthetic ceramic particles for particulate reinforcement of metal matrixes is costly, so locally sourced and sustainable alternatives are sought after Rice husk ash (RHA) at 3–12 wt.%, glass powder (GP) at 2–10 wt.%, and stirring temperature (ST) at 600–800 °C were evaluated for their effects on the elemental distribution, microstructure,andtensileperformanceofaluminum-7075greencomposite.Responsesurfacewasutilizedintheexperimental design and statistical analysis of the experimental results for the purpose of determining the optimal combination of the three input variables. Yield, ultimate tensile, flexural, and impact strengths, as well as microhardness and compressive strength, are examined as responses. To optimize these parameters, response surface analysis was incorporated into the experimental design, modeling, and optimization procedures. Variation in experimental variables led to microstructural evolution, which in turn caused variation in performance. Response surfaceanalysis (RSA)revealed thattheinputfactors contributed significantly to each response, resulting in regression models statistically suited to represent the experimental data, as confirmed by the diagnostic plots. As a consequence of the optimization, a combination of 7.2% RHA, 6.2 GP, and 695 °C with a desirability of 0.91 was deemed optimal. A comparison between the predicted values for the responses and the values from the validation experiment revealed that each response had an error < 5%. Consequently, the models are certified adequate for response prediction with a confidence level of 95%, and the optimal combination is adequate for the composite’s design. | |
