A study of the influence of the tool pin length on the strengthening of the 2024 aluminum alloy under friction stir processing (FSP) was carried out. According to the results of real and model experiments, it was found that for a workpiece with a thickness of 3.0 mm, the necessary and sufficient pin length is 2.0 mm, because in this case, mixing throughout the thickness of the workpiece is provided. It was found that during the FSP of the 2024 alloy, solid-solutional hardening of the processed area occurred due to the release of particles of intermetallic phases.
