| Abstract Scope |
To study the dynamic softening behaviors of 5083 aluminum alloys under hot compression, hot compression tests of 5083 aluminum alloys with extruded and homogenized initial microstructures were conducted at strain rate ranging from 0.1 to 10/s and deformation temperatures ranging from 350 to 450°C. The obtained flow curves under a homogenized initial microstructure were lower than those under an extruded initial microstructure, suggesting that different initial microstructures lead to different microstructure evolution processes. Electron backscatter diffraction (EBSD) was used to observe the microstructure evolution process. The characteristics of continuous dynamic recrystallization, particle-stimulated recrystallization and conventional dynamic recrystallization were confirmed. The experiments deformed at the same temperature and strain rate but with different strains showed the transition from continuous to conventional recrystallization. The recrystallization mechanism of 5083 aluminum alloys with different initial microstructures is thus finally illustrated. |
