In this investigation, through the use of friction stir processing (FSP), the role of vibration and FeAlCrMoNb HEA particles in modifying the microstructure and tribological performance of a novel AZ31/FeAlCrMoNb composite is appraised. The results showed that the application of vibration during FSP can be used as a successful approach for achieving applicable tribological and mechanical features through the use of FeAlCrMoNb particles. Additionally, it was discovered that the utilization of vibration leads to a conspicuous improvement in shear punch strength and hardness concerning traditional FSP that can be attributed to properly scattering the reinforcements across the Mg substrate and eliminating flaws, including the aggregation and gathering of reinforcing powders, achieved by implementing vibration during the process, resulting in enhanced SPT strength.
