摘要

The sustained need for high-strength, low-weight materials drives the research community to develop a sophisticated material to address the emerging industrial needs. The significance of the present research is to improve the flexural attributes by utilizing the process and reinforcement benefits. The Friction Stir Processing (FSP) technique was employed to fabricate the surface composite reinforced through varying weight percentages of two ceramic elements, SiC and Y2O3. The three-point bending test was implemented to investigate the bending attributes. The process benefits were proclaimed by Scanning Electron Microscopy (SEM) and grain size analysis, which revealed that the nugget zone attained finer grain sizes, followed by the mixed coarser-finer grain size at Thermo Mechanically Affected Zone (TMAZ) and blended coarser-zero grain refinement at Heat Affected Zone (HAZ). The flexural examination outcomes manifested a remarkable enhancement of 33% flexural strength and 36.36% flexural modulus for an Al-3SC-1Yo FSPed composite variant than the base material. The post-flexural failure study supported layer sliding as the origin of the failure as a result of the shear stress effect. The numerical analysis performed to authenticate the experimental findings explored the good concurrence between the experimental and numerical outcomes.
