“…The facts that the Masing curve does not completely match up with the upper branches of the hysteresis loops, and the upper branches of the hysteresis loops do not match up with each other indicate that the studied material does not behave like a Masing-type material completely. However, this behaviour does not violate Masing behaviour to a significant extent; hence, the Ramberg-Osgood equation and life prediction models that assume Masing behaviour can be considered valid [20].…”

“…A Masing behaviour is indicated by the upward branches matching up each other, i.e. being theoretically overlapped and standing on the same Master curve [22][23][24]. This curve should be well interpolated by the Masing curve.…”

Turbogenerator coil retaining rings are shrunk-fitted onto the rotor over the coils, in order to restrain them against the centrifugal force. They are typically subjected to low cycle fatigue, with a cycle being completed at every machine switch-on and switch-off. The subject of this paper consists in the determination of the failure probability of a coil retaining ring. The failure mode of the ring cracking, when it swells in tension, due to the centrifugal force is here considered. The reliability assessment is preceded by the study of the input variables affecting the low-cycle fatigue load and of their stochastic distributions. This question is tackled by the experimental determination of the static, cyclic and fatigue curves of the involved material and by the application of a statistical model to compute related parameters and their standard deviations. Upon the determination of variable distributions, the probability of failure is estimated in the form of a cumulative distribution function by a computationally efficient methodology, based on the Advanced Mean Value approach. The obtained results account for the material response and the local stressstrain states at the most loaded coil retaining ring region. The determined probability at the end of the machine life, in the order of 10-12, is compatible with reference values for structures under fatigue in the mechanical and aeronautical fields.

“…1,2 It has been reported that the Hastelloy C2000, with a nominal composition of Ni-23Cr-16Mo (wt-%), resists not only acids over a large range of temperature but also the insidious types of attack induced by chlorides and other halide solutions, specifically pitting, crevice attack and stress corrosion cracking. 3,4 Therefore, the C2000 alloy is a very promising candidate as filter material for dusty gas purification at high temperature. Microstructure can strongly influence the properties and behaviour of polycrystalline materials during processing and in service.…”

Grain boundary character distribution (GBCD) of the Hastelloy C2000 alloy (Ni-23Cr-16Mo) and the effect of coincidence site lattice (CSL) grain boundaries on corrosion resistance were examined by electron backscattered diffraction and electrochemical experiments. Various deformation followed by annealing was applied to optimise the GBCD of the alloy. After grain boundary engineering (GBE) treatment, the proportion of CSL boundaries increased from 37.7% to 62.4% and the corrosion current density of the specimens decreased in NaCl solution. The results indicated that GBE treatment is responsible for preferable corrosion resistance due to the increase of the fraction of special low energy grain boundaries with perfect grain boundary atom arrangement after thermomechanical process.
