The Avrami kinetics of dynamic recrystallization
TLDR
In this article, the double-differentiation method was used to define the critical strain for initiation of DRX and the net softening attributable to DRX was then defined as the difference between the σrecov and experimental curves.About:

Dynamic recrystallization behavior of a typical nickel-based superalloy during hot deformation
TL;DR: In this paper, the volume fractions of DRX were estimated based on the conventional DRX kinetics model and a segmented model was proposed to describe the dynamic recrystallization behavior of a typical nickel-based superalloy.

Constitutive relationships for hot deformation of austenite
TL;DR: In this paper, the authors derived the flow stress of a 17-4 PH stainless steel during hot compression testing using the classical hyperbolic sine equation and the self-diffusion activation energy.

Study on constitutive modeling and processing maps for hot deformation of medium carbon Cr–Ni–Mo alloyed steel
TL;DR: In this article, the hot deformation behavior of medium carbon Cr-Ni-Mo alloyed steel 34CrNiMo was studied in the wide temperature range of 900-1150°C and the strain rate of 0.002-5 s−1.

Kinetics of Phase Change. I General Theory
TL;DR: In this paper, the theory of phase change is developed with the experimentally supported assumptions that the new phase is nucleated by germ nuclei which already exist in the old phase, and whose number can be altered by previous treatment.
Journal ArticleDOI
Kinetics of Phase Change. II Transformation‐Time Relations for Random Distribution of Nuclei
TL;DR: In this article, a relation between the actual transformed volume V and a related extended volume V1 ex is derived upon statistical considerations, and a rough approximation to this relation is shown to lead, under the proper conditions, to the empirical formula of Austin and Rickett.

A unified phenomenological description of work hardening and creep based on one-parameter models
Y. Estrin,H. Mecking +1 more
TL;DR: In this article, a phenomenological treatment of plastic deformation is proposed which makes it possible to describe in a unified way the plastic behavior of a material both under dynamic loading and in creep.

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.

Dynamic recrystallization behavior covering a wide austenite grain size range in Nb and Nb–Ti microalloyed steels
TL;DR: In this article, the dynamic recrystallization (DRX) behavior of Nb and Nb-Ti microalloyed steels has been investigated, and it has been observed that decreasing the values of the Zener-Hollomon parameter and the initial grain size, promotes dynamic re-stallization.
