Full textThe thesis aim is to understand and to model the behavior of Zircaloy-4 during the transport of spent fuel. We developed a model coupling the recrystallisation, the recovery and the mechanical behavior. Electron microscopy confirmed the pre-existent observations on static recrystallisation and showed that the application of a stress influences both the nucleation and the growing of new grain during recrystallisation. The former effect is physically described by adding a term of friction to the recrystallisation model and the latter implicitly included in the coupled modeI. The creep is modelled by a polycristallin mode] to take into account the etTect of the anisotropic behavior of zirconium and microstructure heterogeneity. The local behavior is described by a physically based model which adds a predictive potential to the previous model

Full textThe phenomenon of the decomposition of certain guidelines in fcc crystals rolling is studied by compression experiments on single crystals flat, in parallel with an original theoretical modeling. The heterogeneous deformation of aluminum crystal orientation (001) Kho) is associated with large crystal rotations of opposite directions around DT. The decomposition kinetics are consistent with a Taylor-type models released, while the spatial distribution of deformation bands is explained by a detailed analysis of their plastic deformation incompatibilities. To study the influence of temperature on the hot deformation of crystals, a new compression device bi-recessed flat has been developed (tmax 450c, max 1. 2). Preliminary tests suggest the possibility of a stabilization of the cube orientation has around 400c temperatures. Recrystallization of deformed single crystal of aluminum mechanisms are characterized by SEM micro diffraction (EBSD and ECP). Particular attention is paid to the influence of transition -bt- bands in crystals (001) hko plane after compression. In general, two cases arise: (i) bt germination in a seed with the rotation towards the cube orientation, and (ii) sprouting in the matrix deformation bands with several types of orientation relationships (matrix, to cube or about axes <111>). The orientations of grains after complete recrystallization are also determined and disorientation characterized in terms of the type of grain boundary (method SCL)

Full textHigh speed material forming produces intense and fast strains. The latter, associated with the high speed of deformation inherent to the processes, induce considerable heating of the pieces. Zones of strain localization appear, such as shear bands. On the other hand, other parts of the piece are almost not affected by strain in some cases. Modelling of such phenomena then implies the use of constitutive equations valid over a very wide range of strain, strain rate and temperature. After an overview of torsion tests and results, a compilation of 304L stainless steel available stress-strain curves is presented. A first empirical model, based on the Voce equation, is proposed to describe the rheology of metals in such deformation conditions. All parameters are fitted to the set of experimental curves. This model sets forth two fundamental differences with the classical Johnson and Cook (1983, 1987) constitutive equation. First, the strain, strain rate and temperature effects are coupled together. Second, stress increases with strain until a steady state value. Furthermore, observations of the parameter variations point out a new criterion that defines a range of temperatures and strain rates where recrystallization occurs. A second physical constitutive equation based on discontinuous dynamic recrystallization is then proposed. This model is able to predict the evolution of microstructure during deformation of low stacking fault energy materials. Average grain size and average dislocation density are determined as functions of material parameters. Furthermore, the predicted flow stress correctly represents the shape of experimental stress-strain curves. The full exploitation of the steady state results enables the identification of all parameters. A new method is then proposed to estimate grain boundary mobility. Finally, two simplified versions of the model are proposed to provide solutions suited to finite element codes

Full textAn obvious increase in strain rate is observed during recrystallisation when an alloy is subjected to low stress levels. This phenomenon, known as “Recrystallisation-Induced Plasticity” (RIP), is observed in a number of hot-forming processes. The dominant underlying mechanisms are not yet clear and no constitutive viscoplastic material formulation is available to describe the associated microstructural evolution and mechanical behaviour. This thesis work aims at understanding this phenomenon and developing physics-based models to describe and predict it. In this study, the deformation evolution during recrystallisation is investigated on hot and cold worked Fe-Ni alloys subjected to different relevant temperature-stress conditions. The microstructural characteristics of partially and fully recrystallised materials are first identified through EBSD and TEM observations. The experimental results reveal that deformation accelerations during recrystallisation are mainly associated with the viscoplastic behaviour of recrystallised grains and their evolving volume fraction. Two sets of constitutive equations have been developed to model the RIP phenomenon: (i) one where the material is assumed to be composed of two “phases” (i.e. recrystallised grains and cold-worked grains) and the flow behaviour of the alloy is obtained by homogenising that of each “phase”, and (ii) another where the material is treated as an homogeneous one and where its flow behaviour is assumed to depend on the microstructural “state” described by two internal state variables, namely those associated with strong obstacles and with the recrystallisation volume fraction. The results of this work confirm that a considerable contribution to the deformation enhancement associated with the RIP mechanism arises from viscoplastic deformation by dislocation activity, coupled with a reduction in the dislocation density by recovery processes. This contribution accounts for approximately 70% of the total deformation. It will be shown that this work provides fundamental knowledge to the understanding of the RIP phenomenon which should, in turn, contribute towards improving the control of product dimensioning in hot-forming processes
