The thesis's goal is to study the deformation, at microscopic scale, of the MAX phase Ti2AlN synthesized by powder metallurgy. This work is divided into three parts: in the first part, the interest has been put on the hysteretic behavior of the MAX phases via cyclic mechanical solicitations, during spherical indentation tests and ex-situ compression of micro-pillars, on differently orientated grains beforehand determined by EBSD. In the second part, we were interested into the micro-pillar's deformation via insitu cyclic compression tests coupled with Laue micro-diffraction. The goal was to analyse the evolution diffraction lines during the pillar's deformation in order to highlight the elementary deformation mechanisms and to observe the finale structures via the post-mortem SEM imaging of the pillars. Finally, a last part was devoted to study the deformation mechanisms in temperature at microscopic scale via nano-indentation tests up to 800°C. The characterization of the slip lines on the surface has been revealed by AFM and that of t he microstructural configurations (dislocations) under the indent has been done by TEM. All data collected by these various tests at the small scales have refined our understanding of the deformation mechanisms of crystal MAX phase, particularly with respect to the models usually proposed in the literature

The work concerns the development of new titanium alloys possessing unique properties of plastic deformation (distortion) (a ductility near 3 times superior to the classic alloys) and work hardening. An initial work (CIFRE PhD of Cédrik Brozek, 2013-2016) allowed to transpose approaches used initially on model alloys (Ti-Mo in particular), in materials potentially industrialisables with the aim of applications in the field of the aeronautics. It is on these new industrialisables nuances, based on the system Ti-Cr-Sn that we wish today to base the collaboration with our industrial partner. These alloys possess the capacity to be transformed under constraint, by maclage mechanics and transformation of induced phase, they possess a new combination of properties (a very important ductility accompanied with a work hardening not yet reached in the alloys of titanium) but they are also characterized by a very high microstructural complexity on which we don't possess that much informations for the moment. The project concerns the study of the relations microstructures / mechanical properties in this new family of titanium alloys (alloys "TRIP/TWIP")

It is commonly believed that plastic deformation mechanisms of MAX phases consistin basal dislocation glide, thus forming pile-ups and walls. The latter can form local disorientationareas, known as kink bands. Nevertheless, the elementary mechanisms and the exact role ofmicrostructural defects are not fully understood yet. This thesis report presents a multi-scale experimentalstudy of deformation mechanisms of the Ti2AlN MAX phase. At the macroscopic scale,two kinds of experiments were performed. In-situ compression tests at room temperature coupledwith neutron diffraction brought new insight into the deformation behavior of the different grainfamilies in the polycrystalline Ti2AlN. Compression tests from the room temperature to 900 °Cunder confining pressure were also performed. At the mesoscopic scale, deformed surface microstructureswere observed by SEM and AFM. These observations associated with nanoindentationtests showed that grain shape and orientation relative to the stress direction control formationof intra- and inter- granular strains and plasticity localization. Finally, at the microscopic scale,a detailed dislocation study of samples deformed under confining pressure revealed the presenceof dislocation configurations never observed before in MAX phases, such as dislocation reactions,dislocation dipoles and out-of-basal plane dislocations. In the light of these new results, mechanicalproperties of MAX phases are discussed

Al alloys are widely used for structural application in aerospace, automotive and constructive engineering due to their low density and high strength and for functional application in electrical engineering due to a relatively high electrical conductivity. Precipitation hardening and grain size strengthening are among the main strengthening mechanisms of heat-treatable Al alloys. The precipitation hardening is achieved by artificial aging (AA) and the grain size strengthening could be achieved by several methods, including severe plastic deformation (SPD). The combination of these strengthening effects allows significant improvement of strength of Al alloys. In order to combine these effects, i. E. To design an ultrafine grain structure with nanoscaled precipitates, it is possible to use three different routes: SPD followed by AA; AA followed by SPD or SPD at temperatures of AA. However in practice it turns out to be sometime complex, because of phase transformations induced by SPD in Al alloys. The mechanisms of such phase transformations are still poorly understood. Therefore, the control of microstructure and as a consequence the control of properties becomes very difficult. Therefore, in this work, the first step was to determine the microstructure changes occurring in Al alloys under SPD and to understand the underlying mechanisms of microstructure evolution. In a second step we have also quantified the relationship between structure and mechanical and electrical properties. To reach these goals, model Al-Cu and industrial Al-Mg-Si alloys were studied using Transmission Electron Microscopy (TEM), Atom Probe Tomography (APT), microhardness measurements and electrical conductivity measurements. Alloys were subjected to SPD by high pressure torsion (HPT) under different processing conditions to reveal the influence on microstructure and properties. It is shown that HPT at ambient temperature leads to the decomposition of solid solutions for both Al alloys and dynamic precipitation at grain boundaries only for Al-Cu alloy. The solute drag by grain boundaries motion was identified as the main mechanism supporting the decomposition of solid solutions. The precipitation in the Al-Cu alloy occurs due to an increase of Cu concentration at GBs and a high Cu GB diffusivity. Besides, the optimum thermomechanical treatment, combining HPT and post-deformation heat treatment was also determined in order to optimize the combination of high strength and electrical conductivity

The thesis aims to understand the influence of the metallurgical state of austenite at high temperature on the phase transformation mechanisms in two model grades of low carbon steel: 0.06%C-2.4%Mn-0.3%Si (CMn-1) and 0.2%C-2.4%Mn-0.3%Si (CMn-2). A series of heat treatments enabled a thorough crystallographic analysis of the transformation products according to the γ grain size. According to the numerous microstructures obtained, the advantages and limits of the crystallographic reconstruction of austenite from EBSD data are defined according the type of inherited microstructures. Finally, hot compression tests at 800°C (Ar3+100°C) are performed on the grade CMn-1 to follow the evolution of the austenitic microstructures and microtextures based on strain conditions. The characteristics obtained by crystallographic reconstruction are confirmed by an analysis of the 30%Fe-70%Ni hot-rolled model alloy. We identified high misorientations in the vicinity of grain boundaries and two characteristics deformation substructures: grains homogeneously deformed by planar slip mechanism and grains with deformation microbands. These structures depend on the components of texture developed in the austenite. It was found that the bainitic laths are promoted as the deformation increases to the detriment of the martensite formed by quenching, resulting in a decrease of the hardness. Moreover a granular structure also grows along prior [gamma] grains boundaries and spreads across the grain during isothermal bainite transformation at 525°C. Lamellar microstructures are aligned along the most active slip plans {111} [gamma] in homogeneously deformed grains, while the nucleation of small bainitic areas with different orientations is promoted in the microbands
