TLDR
In this article, the effects of dissolved carbon and testtemperature on the development of fatigue damage in a low-carbon steel were investigated using optical and electron microscopy, and it was concluded that active slip bands are not effectively strengthened by strain ageing during continuous cycling.About:

Plastic strain localization in metals: origins and consequences
TL;DR: In this paper, the mechanisms and consequences of plastic strain localizations exhibited in tensile stress-strain behaviors, fracture and fatigue are discussed, including important practical considerations and historical background; then dislocation mechanics based details are developed in subsequent sections.
Journal ArticleDOI
Cyclic Slip Irreversibilities and the Evolution of Fatigue Damage
TL;DR: In this article, the physical origin of fatigue crack initiation in ductile metals is discussed from a historical perspective, and the cyclic slip irreversibilities in a microstructural sense that occur not only at the surface but also in the bulk at the dislocation scale are assessed.

Coarse slip model of fatigue
TL;DR: In this article, a model for the formation and propagation of cracks is developed which satisfies many well known general features of fatigue as well as the results of new observations of the fracture surface features of single crystals of copper.

The dislocation distribution in face-centred cubic metals after fatigue
TL;DR: In this article, annealing of dislocation loops was investigated for stainless steel fatigued at high stress, showing that the loops are elongated in a direction normal to the Burgers vector, suggesting strongly that they are formed from sessile jogs in screw dislocations.

Interaction of dislocations and precipitates in quench-aged iron-carbon alloys subjected to cyclic stressing
J.T McGrath,W.J Bratina +1 more
TL;DR: In this paper, an Fe-0.08 wt.%C alloy in the quench-aged condition was examined by optical and transmission electron microscopy and the resultant microstructure has been examined.

The effects of dislocation locking and strain ageing on the fatigue limit of low-carbon steel
G Oates,D.V Wilson +1 more
TL;DR: In this article, the role of initial dislocation locking and strain aging in the development of the fatigue limit of a low-carbon steel was investigated, with the object of clarifying the roles of initial locking and of strain ageing.

Substructure of Persistent Slip Bands in Cyclically Deformed Copper
TL;DR: In this paper, the dislocation distribution in the surface layer of cyclically deformed specimens of polycrystalline copper is studied by means of transmission electron microscopy of thin foils, both parallel and non-parallel to the surface.
