Full textThe late neolithic - chalcolithic of western languedoc and roussillon is identified as saintponian and verazien. The occupation of chasseen sites continues, but new territories are occupied the distribution of sites obeys abiotope selection following diverce geographical factors. Divelling structures are represented by enclosures, pits, scaltered artefacts and huts, solely in a circular or elongated - hemiocircular form. Funeral rites shows insividual or collective burials. The economic activities in middle neolithic continue, except for commercial exchanges. Lithic industries contain blades and bladelets, flaked implements and a roughly-made a macro-industry. Arrourheads are triangular, non-symetric, leaf or stem shaped. The abondance and diversity of material in bone or antler is notable in the saintponian late neolithic. Ornements are more recognisable in other neolithic groups in southern france. Pottery is divised between four simple open forms, four simple closed forms and six more complex forms with caree. The decorative element of pastilles and grooves supplement the functional elements of prehension. An evolutive model, based upon storage jars, proposes six styles. Following this hypothesis, some sites indicate long occupations, corresponding either to a durable settlement or to short, repeated stays. .

Full textThe need to reduce the fuel consumption of vehicles while increasing safety led the automotive industry to develop a 3rd generation of Advanced High Strength Steels. Such steels combine innovative processing routes, complex microstructures, improved mechanical properties and are a possible response in vehicle lightweighting. The Quenching and Partitioning (Q&P) process is the most promising route and involves quenching below the martensite start temperature followed by a reheatingand ageing above the initial quench temperature (QT). The ageing step is termed “partitioning step” since carbon enrichment in austenite is expected to occur during this stage. The exceptional mechanical properties of Q&P steels come from their complex duplex microstructure: very fine austenite island retained at room temperature embedded in both recovered and fresh martensite. Although the mechanisms of carbon enrichment in retained austenite during the partitioning step are still debated,strong evidences of carbon partitioning from martensite to austenite exist. However, both the formation of bainite and carbides into martensite raise the question of the effects of competitive reactions on the carbon enrichment in austenite. It is clearly a topic of interest since the benefits of such a treatment in terms of improved mechanical properties depends strongly on the austenite stability and thus on the level of carbon enrichment in austenite during the partitioning step.This thesis aims at combining an innovative multiscale experimental methodology with an original theoretical approach providing a unique opportunity to give some clarifications regarding the microstructure evolution and the mechanisms of carbon enrichment into austenite. After having determined the optimum Q&P parameters using dilatometric and XRD measurements, a Q&P treatment at three different QT (260, 230 and 200°C) and at a partitioning temperature of 400°C was applied to a model Fe-0.3 C-2.5Mn-1.5Si steel. The dilatometric data combined with an SEM image analysis study showed that bainite forms during the partitioning step. The presence of bainite was also confirmed by in-situ High Energy X-Ray Diffraction. While bainite was shown to appear as carbide free laths, tempered martensite showed an advanced state of intra-lath precipitation. The combination of atom probe tomography (APT) and TEM technics showed that theses carbides are transitional andboth η and ε carbides were observed. Their carbon content ranged from 20.0 to 27.7 at.%. APT measurements also highlighted carbon segregation on martensite defects during the initial quench and calculation of the evolution of the carbon excess concentration on laths boundaries suggest that desegregation occurs along the Q&P treatment. In-situ HEXRD permitted to follow the austenite lattice parameter evolution and it was shown that austenite is subjected to a sequence of tensile andcompression state induced by the formation of martensite. A model for the coefficient of thermal expansion of austenite taking into account its stress state was successfully developed. The evolutions of carbon content into austenite for the three QT were determined. Surprisingly the carbon enrichment into austenite was shown not to depend on QT. It was also shown that the increase of carbon content in austenite results from both carbon partitioning and bainite contributions. Lastly, an originaltheoretical approach was developed. It was evidenced that bainite continues to form while partitioning process is rapidly completed, thus bainite transformation controls the maximum austenite carbon enrichment at 400°C, independently of QT. The contribution of partitioning from martensite was shown to be larger with decreasing QT. The developed model successfully described the experimentally observed phase transformations and austenite carbon enrichment by taking into account theinteractions between carbon partitioning, bainite transformation and carbide precipitation

Full textLead calcium tin alloys are extremely used as electrodes in acid batteries. They are structural hardening alloys, synthesized by casting/hardening and subject to microstructural evolution during use. The change from an "aged" metallurgic structure to an "over-aged" structure is associated, in particular, with a decrease of mechanical properties. The aged state can be stabilized with an optimization of the structural hardening process. The thermodynamic modeling of the PbCaSn system has been performed according to the CALPHAD approach in order to appreciate the oversaturation degree after casting and to optimize the necessary thermal treatment to obtain the stabilization of the aged state. A new elaboration process has been developed. It is based on Pb/TiO2 composite synthesis by hot compaction (sintering). Even if the electrochemical properties are not optimized, mechanical properties are improved in comparison with PbCaSn alloys synthesized by die casting and stabilized in aged state
