On the Onset of Dynamic Recrystallization in Steels

open access: yesAdvanced Materials Research, 2011
The knowledge of the flow behavior of metallic alloys subjected to hot forming operations is of particular interest for designers and engineers in the practice of industrial forming processes simulations (i.e. rolling mill). Nowadays dynamic recrystallization (DRX) is recognized as one of the most relevant and meaningful mechanisms available for the ...

Deformation-activated recrystallization twin: New twinning path in pure aluminum enabled by cryogenic and rapid compression

open access: yesiScience, 2022
Summary: 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 × 104 s−1) impact at a
