The polycrystalline nickel-base superalloy RR1000 is used as turbine rotor material in Rolls-Royce aero engines and has to withstand a wide variety of load and temperature changes during operation. In order to maximize the potential of the material and to improve component design, it is of great interest to understand, and subsequently be able to a...

The crack driving mechanisms in a coarse grained nickel-base superalloy RR1000 when subjected to in- and out of phase thermo mechanical fatigue are investigated. It is found that the difference in fatigue crack growth rate between these two load conditions is accounted for by the different mechanical conditions at the crack tip region, rather than...

... As the aim of this paper is to quantify the effect of scatter in constitutive parameters to the obtained scatter in the predicted fatigue crack initiation life, the material data and response of the coarse-grained version of the powder-processed γ ′ -strengthened polycrystalline nickelbase superalloy RR1000 has been investigated, see e.g. Engel et al. [30]. The constitutive behaviour and the TMF crack initiation life, using a fatigue damage accumulation model, under a flight representative load cycle of this material has previously been modelled with success, see Leidermark et al. [20]. ...
... In recent years, a lot of studies on TMF characteristics have been reported for several types of materials, such as 9% Cr steel [14][15][16][17], nickel-base alloys [18][19][20], titanium-aluminide alloys [21,22] etc. In addition, with the rapid development and broad application of 300 series austenitic stainless steel, the TMF behaviour of 300 series austenitic stainless steel has become a hot spot in the field of high-temperature structural integrity [23][24][25]. ...
