Effect of dwell time between passes on recrystallization behavior of 4043 aluminum alloy
In this paper, the recrystallization behavior of 4043 aluminum alloy under the deformation conditions of dwell times of 1 s, 10 s, 30 s, and 90 s between passes was studied. The results show that when the inter-pass dwell time is increased to 10 s, the instability region in the material hot processing map disappears. Additionally, particle-stimulated nucleation (PSN) predominantly occurs at low deformation temperatures and in specimens with short inter-pass dwell times under high deformation temperatures. Importantly, at a deformation condition of 450 °C and a strain rate of 0.01 s−1, when the inter-pass dwell time is increased to 90 s, the alloy texture type changes from a strong Goss texture to a strong rotated cube texture, with the primary recrystallization mechanism shifting from PSN to continuous dynamic recrystallization (CDRX). A longer dwell time of 90 s tends to achieve the maximum static softening rate and a higher recrystallization fraction (8.54%). These findings reveal the impact of inter-pass dwell time on the hot deformation behavior of 4043 aluminum alloy, providing theoretical guidance for industrial production.
Graphical abstract
The effect of dwell time on recrystallization behavior and the recrystallization mechanism of PSN were studied.
期刊介绍：
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
