Abstract The present study investigates the microstructural evolution and damping behavior of AA2024 aluminum alloy subjected to friction stir processing (FSP), with emphasis on establishing a quantitative structure–property relationship across multiple length scales. Optical microscopy and ImageJ analysis showed a considerable reduction in average grain size, from 58 ± 11 µm in the base alloy to 5.4 ± 1.3 µm in the stir zone, indicating extensive refinement and homogeneity.
