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 ...

The American Journal of Occupational Therapy, 1994
Abstract Objectives. A review of outcome research conducted between 1982 and 1992 revealed return-to-work rates for industrial rehabilitation programs that ranged from 50% to 88%. Variations in outcome statistics appeared to reflect discrepancies in factors such as type of research design, initial characteristics of the client sample ...

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.

Metal Science, 1983
AbstractUntil recently some authors of papers and textbooks have given the erroneous impression that increased work hardening rate always leads to increased maximum uniform strain. Recently, it has been recognized that such a statement is true only if the tensile strength remains constant.

1992
Following Drucker (1951,1959), we introduce the concept of stability of deformation processes. We use the so-called quasi-cycle for stresses, e.g. a process in which the stress after loading and unloading returns to its initial state, but the strain state in general does not (through irreversibility of plastic processes). Fig. 8.1 shows the quasi-cycle

Work rehabilitation programs: work hardening and work conditioning
2006According to the American Commission for Accreditation of Rehabilitation Facilities (CARF), work hardening (WH) is “a highly structured, goal-oriented, individualised treatment program designed to maximise the ability to return to work, addressing the issues of productivity, safety, physical tolerances, and work behaviours” [1].

Work-hardening in superlattices
Acta Metallurgica, 1969Abstract The work-hardening in superlattices is critically analyzed based on experimental observations in single crystals of Cu 3 Au and Ni 3 Fe (L1 2 structure). The most important consequences resulting from the existence of superdislocations are the formation of relatively strong recombinations of moving dislocations with attractive “trees” and ...

Outcome Analysis of Work-Hardening Programs
The American Journal of Occupational Therapy, 1993Abstract The competitive marketplace and the demand for accountability by health care payers are strongly influencing the need for work hardening programs to participate in program evaluation and produce outcome data. This study compiled program performance data on 22 work programs in Wisconsin over an 11-month period.

Canadian Journal of Physics, 1967
A theory of single-slip work hardening is proposed, in which the flow stress is controlled by the stress required for one group of dislocations to pass another group with the same Burgers vector but with opposite sign on a parallel slip plane. The strain and the details of the slip-line pattern are calculated as a function of stress from the known ...

Work-hardening of metal crystals
Czechoslovak Journal of Physics, 1966Some recent problems relating to work-hardening of metal crystals, such as the contribution of dislocation stress fields to the flow stress, the mechanism of the second stage, or linear, hardening, and the transition to the strongly temperature dependent third stage are discussed.
