A consistent research attempt to develop newer lightweight-high strength materials facilitates the automobile sector excel in product efficiency. The present is another endeavour anchor industries by exploring novel composite. different earth elements SiC and Y2O3 are utilised for hybrid reinforcement of Al 5052 alloy four weight proportions. Friction Stir Processing (FSP) employed fabricate composites. microstructure analysis conducted through optical microscope reveals formation fine grain size at nugget zone. effect dynamic recrystallization particulate strengthening reflected inflated tensile Al-3SiC-1Yo. microhardness test results manifest higher hardness zone descending Heat Affected Zone (HAZ) Thermo Mechanically affected (TMAZ). post-tensile fracture morphological observation Scanning Electron Microscopy (SEM) explores mechanisms offered piled-up dislocation densities. hard particle inclusion matrix helps achieve 63.87 %, 50 % 35 improvement strength, impact toughness reinforced FSPed alloy. Further, a level beyond 0.5 found dent properties due agglomeration particles.
