Abstract
This work is devoted to the study of the effect of sliding at velocities close to those achieved during friction stir welding or friction drilling on the microstructural evolution of 2024 aluminum alloy. The distribution of both solid solution grains and intermetallic precipitates is analyzed. No layers of recrystallized grains depleted by precipitates, which is a common finding in FSW or friction drilling, are found below the worn surface independently of the sliding velocity. A small precipitate content and size changes alone are observed.Keywords
