In this paper, the historical context of the development of what is now known as ‘Fracture Mechanics’ is selectively developed. We start from the safety and economic motivations, and review the essential efforts, over the centuries, to develop th

Single-crystal Ni-base superalloys are a favoured material for blades in the hot section of aero turbines. These materials exhibit excellent dimensional stability, deformation response and oxidation behaviour at higher temperatures, relative to other

Thermomechanical fatigue (TMF) is a low cycle fatigue process in which material life is correlated to the mechanical strain amplitude. However, it is well known that several other factors influence this life. This paper examines several of these para

The aging of the microstructure of Ni-base superalloys during service is primarily characterized by coarsening and rafting of the γ ′ precipitates. The influence of these different aged microstructures on thermomechanical fatigue (TMF) under eithe

The Portevin-Le Chatelier (PLC) effect has been studied in the Ni-based superalloy IN100 which is currently used as a disk material in jet engines. A series of tensile tests was carried out at 588 K, 755 K, and 922 K (315 °C, 482 °C, and 649 °C) a

This research looked at the effect of crystallographic orientation and temperature on the fatigue crack growth rate and the resulting fracture surface morphology in PWA1484 single crystal superalloy. Two groups of single edge notch tension specimens,

Thermomechanical fatigue (TMF) is the life-limiting damage phenomenon occurring in gas turbine components. Laboratory TMF tests are traditionally used to simulate the operating conditions inside of the turbine. However, typical LCF laboratory TMF tes

This article focuses on the mechanisms and consequences of plastic strain localizations exhibited in tensile stress–strain behaviors, fracture and fatigue. A broad overview is first presented, including important practical considerations and histor

An approach was developed to predict the thermo-mechanical fatigue crack growth rates under typical gas turbine engine spectrum loading conditions. The material studied in the development of this model was a polycrystalline superalloy, Inconel 100. L
