Microstructural simulation of dynamic recrystallization [PDF]
Acta Metallurgica et Materialia, 1992 A Monte Carlo model for dynamic recrystallization has been developed from earlier models used to simulate static recrystallization and grain growth. The model simulates dynamic recrystallization by adding recrystallization nuclei and stored energy continuously with time.

Evidence of dynamic recrystallization in polar firn [PDF]
Journal of Geophysical Research: Solid Earth, 2009 Microstructural analyses have been performed on polar firn from the European Project for Ice Coring in Antarctica drilling site in Dronning Maud Land, Antarctica. The results derived from images of the firn structure in microscopic resolution indicate that dynamic recrystallization is active in firn at all depths, and it dominates the evolution of the ...

On the Onset of Dynamic Recrystallization in Steels
Advanced 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 ...
