摘要	Ultrafine-grained (UFG) and coarse-grained (CG) AA2024 samples are prepared by powder metallurgy process involving high-energy ball milling, spark plasma sintering and hot extrusion, as well as subsequent T6 heat treatment. The microstructural evolution, precipitation behavior, and tensile mechanical properties of the samples are investigated. During T6 heat treatment, recrystallization and grain growth occur, leading to a grain coarsening in the CG2024 sample and a slight grain refinement in the UFG2024 sample. After T6 heat treatment, the UFG2024 sample demonstrated an accelerated precipitation behavior with the formation of lens-shaped and round S' phases due to the high density of dislocations and grain boundaries. This consequently resulted in an improvement in both strength and tensile ductility. Based on the analysis, nanoparticle strengthening and grain boundary strengthening make the major contributions to the improved yield strength of the UFG2024-HT sample.
