TLDR
In this paper, the low cycle fatigue and fatigue crack propagation of Inconel 718 alloy and Waspaloy were investigated at 25, 550 and 650 °C and the qualitative observations indicate that there exists a close correspondence between the near-threshold regime and stage I crack initiation in low-cycle fatigue.About:

Nickel-Based Superalloys for Advanced Turbine Engines: Chemistry, Microstructure and Properties
Tresa M. Pollock,Sammy Tin +1 more
TL;DR: The chemical, physical, and mechanical characteristics of nickel-based superalloys are reviewed with emphasis on the use of this class of materials within turbine engines as mentioned in this paper, and the role of major and minor alloying additions in multicomponent commercial cast and wrought super-alloys is discussed.

On the origin of planar slip in f.c.c. alloys
TL;DR: In this article, the origin of planar slip in single-phase and precipitation-hardened f.c. alloys is discussed in detail, and it is shown that pronounced short range order (SRO) or short range clustering (SRC) in solid solutions are the main reasons causing plan-ar slip.

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.

High temperature fatigue of nickel-base superalloys - A review with special emphasis on deformation modes and oxidation
TL;DR: In this article, a review of Ni-base superalloys in terms of fundamental deformation mechanisms, environmental effects, and interactions between environment and deformation mode is presented, where the basic principles that are developed are used to show how both intrinsic and extrinsic variables can be manipulated to control fatigue behaviour and as a guide for formulation of engineering life prediction models.

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.

Fatigue at High Temperature
TL;DR: In this article, the state of the art of high temperature fatigue is reviewed, focusing on the relative rotes of crack initiation and crack propagation, to damage processes resulting from cyclic strain including that of the substructure, of cyclic strains aging, at grain boundaries, by the environment, from wave shape effects and from plastic instabilities.
