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.

Annihilation of dislocations during tensile and cyclic deformation and limits of dislocation densities
U. Essmann,Haël Mughrabi +1 more
TL;DR: In this paper, it was shown that the critical spacings of dislocation pairs that annihilate are ∼.50-500 nm for screw and ∼ 1·6 nm for non-screw dislocations.

Prediction of steel flow stresses at high temperatures and strain rates
A. Laasraoui,John J. Jonas +1 more
TL;DR: In this paper, the flow behavior of steels during deformation in the roll gap was simulated by means of single hit compression tests performed in the temperature range 800 °C to 1200 °C.

Dislocation Velocities, Dislocation Densities, and Plastic Flow in Lithium Fluoride Crystals
W. G. Johnston,John J. Gilman +1 more
TL;DR: In this paper, the authors measured the velocities of individual dislocations in LiF, covering a range of twelve orders of magnitude in velocity, from 10−7 cm/sec to 105cm/sec.

A model for yielding with special reference to the yield-point phenomena of iron and related bcc metals
TL;DR: In this article, a model for yielding based on dislocation multiplication and velocity characteristics specific to iron and related b.c. metals is derived on the premise that dislocations anchored by segregates or precipitates remain locked.

Dislocation dynamics in deformation and recovery
TL;DR: Phenomenological equations between dislocation velocity, effective shear stress, temperature, and pressure are presented in this article, where it is suggested that the term "activation volume" be properly assigned to t...

Components of the flow stress of iron
TL;DR: In this article, tensile tests have been made on a pure iron (99.97% pure; interstitial content 0.007 at) covering a total grain size range of 0.025-2 mm and a temperature range of −196 to +400°C.
