Abstract

This study examines the effects of vibration and AlCrFeMoNb HEA particles on the structure and wear properties of a novel AlCrFeMoNb/AZ80 composite, utilizing friction stir processing (FSP). The findings demonstrated that in comparison to the FSPed sample, the gains in the stir zone of the FSVPed sample demonstrated not only more refining of grains, but also homogeneous dispersion of AlCrFeMoNb particles in the matrix. The effectiveness of FSVP was evident in the enhanced fragmentation of reinforcing particles dispersed in the matrix, which led to a decrease in the mean grain size and significantly improved the shear punch strength. This phenomenon is associated with the elimination of flaws as well as proper scattering of AlCrFeMoNb particles across the matrix.
