A one-parameter approach to determining the critical conditions for the initiation of dynamic recrystallization
E.I. Poliak,John J. Jonas +1 more
TL;DR: In this article, the onset of dynamic recrystallization is treated in terms of a model based on the principles of irreversible thermodynamics, and the model is verified using experimental data obtained during the high temperature compression of nickel and of a type 305 austenitic stainless steel.

Development of dynamic recrystallization theory
TL;DR: In this article, it was shown that the grain boundary serrations meet across the elongated thinned grains thus pinching them off into almost equiaxed grains containing a substructure, thus geometric DRX.
