Synergistic Enhancement of Strength and Ductility in 2024Al Alloy via Deliberate Integration of Grain Refinement and Precipitate Strengthening
Ultrafine-grained (UFG) 2024 aluminum alloys with a heterogeneous lamellar structure were fabricated by powder metallurgy routes, including spark plasma sintering and low temperature hot extrusion. Subsequent deliberate short-duration solution (495 °C/25 min) and aging (150 °C/10 h) treatments preserved the UFGs while inducing dense nano-sized α-AlMnSi precipitates, resulting in superior mechanical properties, i.e., yield strength of 391 MPa, ultimate tensile strength of 522 MPa and uniform elongation of 12.7%. The synergistic strength-ductility enhancement originates from the precipitation strengthening of nano-sized α-AlMnSi precipitates, grain boundary strengthening of UFGs as well as the pinning effects of MgO particles at grain boundaries. The study highlights an effective approach to achieving superior strength and ductility in aluminum alloys through optimized processing and heat treatment, offering valuable insights for the development of high-performance aluminum alloys in diverse industrial applications.
