Full textPrecipitation hardened martensitic stainless steels are constitutive of aircraft pylons. During there lifetime , these parts are subjected to mechanical loading and work in temperature. This last induces embrittlement of the steels, because of the miscibility gap in the Fe-Cr phase diagram. Two mechanisms are possible to lead to the demixing of the matrix, either precipitation of α', a chromium rich phase, or spinodal decomposition mechanism. This phenomena is the topic of the project PREVISIA, funded by the ANR, this work is part of. Long term agings have been performed on 15 5 PH stainless steel up to 15 000 hours in order to study the aging kinetic and its effect on the mechanical properties in tensile, resilience and toughness. An embrittlement of the alloy is observed. Furthermore, microstructural analyses have been conducted and lead to the definition of different stages of long term aging corresponding to spinodal decomposition and complementary precipitation of hardening phase. Hardness tests is a usefull tool in order to follow the aging and to detect the different stages of aging. The effect of a stress applied during the long term aging has been studied. A tensile stress seems to have an influence on the complementary precipitation of the hardening phase and to increase the rate of hardening. A multi-scale analysise is proposed in order to explain all these results

Full textThe present work focuses on the high temperature mechanical behaviour of 9%Cr tempered martensite steels, considered as potential candidates for structural components in future Generation IV nuclear power plants. Already used for energy production in fossil power plants, they are sensitive to softening during high-temperature cycling and creep-fatigue. This phenomenon is coupled to a pronounced microstructural degradation: vanishing of subgrain boundaries, decrease in dislocation density, nucleation and/or growth of precipitates and new phases. This study aims at (i) linking the macroscopic cyclic softening of 9%Cr steels and their microstructural evolution during cycling and (ii) proposing a physically-based modelling of deformation mechanisms in order to predict the macroscopic mechanical behaviour of these steels during cycling. Mechanical study including uniaxial tensile tests and cycling at 550 °C was performed on a Grade 92 steel (9Cr-0,5Mo-1,8W-V-Nb). Examination of tensile specimens suggested that the physical mechanism responsible for softening is mainly the evolution of mean subgrain size, which increases by more than 15 % compared to the as-received state. The evolution of macroscopic stress during cycling shows that cyclic softening is due to the decrease in kinematic hardening. TEM observations highlighted that the mean subgrain size increases by 65 to 95 % while the dislocation density decreases by more than 50 % during cycling, compared to the as-received state. A self-consistent homogenization model based on polycrystalline elastoviscoplasticity, predicting the mechanical behaviour of the material and its microstructural evolution during deformation is proposed. This model takes the physical deformation mechanisms into account and only two adjustable parameters (activation energy and activation volume) linked to the viscoplastic deformation mechanisms are used. The value of other parameters were either experimentally measured or deduced from computations available in literature. The model correctly predicts the macroscopic softening behaviour and gives a good trend of the microstructural evolution during cycling. The parametrical study shows that the predictions of the model are rather stable with respect to the variation of the physically-based parameters. Finally, some hypotheses which permit us to improve the model are presented and torsion tests (with or without constant superimposed tensile stress) are modeled
