2+ ZrO 2 composite by using the friction stir processing method. The local shear punching
strength, structure, hardness, and wear of the hybrid AZ80 Mg/CeO 2+ ZrO 2 composite were
investigated. A change of the tool profile from cylindrical to conical pin profile eliminates
particle clusters and inherent voids while the nugget shape, vortex width, and surface flash
are also affected due to the tool's volumetric difference. Microstructural changes (grain and …
