Dynamic recrystallization of minerals

WebHigh-temperature plane-strain compression tests were performed on Fe-3.0 wt.% Si alloy from 900 °C to 1150 °C at strain rates of 5 s−1 to 1 s−1, and the texture development from different initial textures was investigated by means of electron backscattered diffraction. Dynamic recrystallization occurs by strain-induced boundary migration, and the … WebThese reactions catalyze dynamic recrystallization of iron oxide minerals through localized and simultaneous oxidative adsorption of Fe(II) and reductive dissolution of Fe(III). Redox-active trace elements undergo speciation changes during this process, but the impact redox-driven recrystallization has on redox-inactive trace elements ...

WebJan 20, 2024 · The existence of dynamic recrystallization (DRX), i.e., recrystallization occurring during straining, has long been questioned [] despite the publication of strong mechanical and microstructural evidence [].Some authors later showed that it was not merely a “laboratory curiosity” but in fact a real “industrial tool” [].Currently, DRX has … Continuous dynamic recrystallization is common in materials with high stacking-fault energies. It occurs when low angle grain boundaries form and evolve into high angle boundaries, forming new grains in the process. For continuous dynamic recrystallization there is no clear distinction between nucleation and growth phases of the new grains. Continuous Dynamic Recrystallization has 4 main characteristics:

WebRésumé (eng) Recent experiments and theories on static and dynamic, solid state, deformation induced recrystallization are reviewed.
