WebMay 5, 2024 · Bulk aluminum rarely forms deformation or annealing twins owing to its high stacking fault energy. We report a novel twinning mechanism mediated by dynamic recrystallization in 6N pure aluminum under high strain rate (∼1.3 × 104s−1) impact at a cryogenic temperature (77 K). Web2 days ago · Lin et al. [10] were found that dynamic recrystallization could take place in some aluminum alloys such as Al-Zn-Zr, Al-Cu-Mg and AI-Mg alloys. There is some evidence that discontinuous dynamic recrystallization (DDRX) would be the main softening process during hot deformation of Al–Mg–Mn alloys.
