Journal of Applied Mechanics, 1948
Abstract Based on the “blocking” theory of the strength of a poly-crystalline metal, a law of work-hardening is derived and checked experimentally on mild steel deformed by wire-drawing up to a deformation of 4.6 in the logarithmic measure.

A model comprising work hardening and solid solution hardening
Physica Status Solidi (a), 1978In a former paper the problem of solid solution hardening and work hardening of solid solutions was treated for the case of two types of obstacles with relative concentrations xs and xw, and strengths ƒs and ƒw. The resolved shear stress can be formally written as τ2/(Gb/l0)2 = τ(ƒs, ƒw, xs, xw) where G and b have their usual meaning and l0 denotes ...

Work hardening of dispersion-hardened crystals
Philosophical Magazine, 1966Abstract A new theory of work hardening in dispersion-hardened single crystals—by which we mean soft crystals containing hard non-deforming particles of a second phase—is described. It is based on the fact that, if the particles do not deform plastically, and the interface between particle and matrix does not fracture, then secondary slip must occur ...

Work-hardening and recovery of dispersion hardened alloys
Philosophical Magazine, 1976Abstract Experiments have been carried out in order to test theories of the work-hardening and low temperature recovery in dispersion hardened crystals. Single crystals of copper containing small (∼ 500 A diameter) particles of SiO2 have been deformed in tension at temperatures between 77 and 450 K, and the primary and secondary dislocation ...

Physical Review, 1952
Two kinds of work-hardening are discussed, interaction-hardening and source-hardening. Interaction-hardening arises because a large stress must be applied to move a dislocation through a material which already contains a large number of dislocations.

Materials Science and Engineering: A, 1997
This paper presents simulation of the work hardening curves of metals deformed at a constant temperature and strain rate under conditions of dynamic recrystallization (DRX). A work hardening model has been developed based on the evolution of the dislocation structure during deformation.

Work Hardening and Work Conditioning
1998Since their inception in the late 1970s, work-hardening and work-conditioning programs have undergone metamorphoses. They have become less distinct and now offer more diverse services. This is primarily due to the ever-changing environment of health care, and the need to adapt to new consumer needs.

On the Work Hardening of Superstructures
physica status solidi (b), 1968AbstractThe mechanism for the work hardening of superstructures proposed by Vidoz and Brown is modified. It is shown that this model explains the experimental results even when only a very small increase in the forest density, possibly too small to be observed experimentally, takes place during deformation.

Plastic Deformation and Work Hardening in NaCl
physica status solidi (b), 1964AbstractSingle crystals of NaCl were compressed at room temperature. The stress‐strain curve shows three well‐defined stages similar to those found for fcc. metals. The dislocation density, bulk density, and deformation characteristics were studied as functions of stress and strain. The recovery of the dislocation density and bulk density were compared
