Characterization of hot workability of IN617B alloy using activation energy, Zener-Hollomon parameter and hot processing maps

open access: yesJournal of Materials Research and Technology, 2023
In order to predict the hot workability of the material more accurately, this paper takes the hot deformation of IN617B as the example. The activation energy (Q) map, Zener-Hollomon parameter (Z) map, and hot processing map were established based on the ...

Mechanisms of Dynamic Recrystallization in Aluminum Alloys

open access: yesMaterials Science Forum, 2014
Mechanisms of dynamic recrystallization operating at severe plastic deformation in a wide temperature range are reviewed for aluminum alloys. The main mechanism of grain refinement in all aluminum alloys is continuous dynamic recrystallization (CDRX).

Dynamic Recrystallization of a Quartz Porphyroclast [PDF]

open access: yesTexture, Stress, and Microstructure, 1991
Dynamic recrystallization occurs to minimize strain energy via either grain boundary migration or subgrain rotation1,2. Both result in similar microstructures, but whereas in the former new grains have their crystallographic orientation controlled by neighbouring grains, in the latter new grains are derived from the parent grain.
