During the nitriding treatment, the diffusion of nitrogen in the steels causes the transformation of initial carbides into nitrides. During this transformation, carbon is released into the ferritic matrix. The experimental study has highlighted that the decarburization of the nitride layer occurs regardless of the type of nitriding and could reach 20% when the nitriding surface is not composed of compound layer This decarburization is induced by the reaction of the carbon released during the transformation of the cementite, with the hydrogen produced by the decomposition of ammonia to give a carburized species ?, this reaction occurs as long as any compound layer exists at the surface of the sample. This carbon redistribution has an influence on the microstructure and the residual stresses of the nitride layers. Based on experimental results, this phenomenon has been implemented in the nitriding simulation model developed in the laboratory. This implementation focuses on initial and boundary conditions obtained by complementing the experimental results with a thermodynamic simulation, to simulate nitrogen and carbon profiles close to those obtained experimentally. The model also calculates the volume change due to ? the precipitation and calculates the fields of residual stresses generated at the nitriding temperature and their evolution during cooling.. The multiphase character of the material is taken into account; the simulation allowing knowing the residual stresses in the ferrite, the precipitates and macroscopic residual stresses through a micromechanical model of scale transition like self-consistent. This multiphysics approach is applicable to all alloy carbon steels (Cr, Mo, V). This model has specifically been applied to industrial grade 33CrMoV12-9. The entire study allows understanding the influence of carbon on the mechanical properties of nitrided layers and the development of an industrial nitriding cycle based on experimental results and simulation

Pearlite is a common constituent of a large variety of high strength steel grades typically used in many structural engineering applications, which demand a good combination of high strength and ductility. With the increasing requirements for product quality and in-service reliability, the non-destructive inspection of materials enables the evaluation of their properties including electromagnetic methods, such as eddy current testing (ECT). However, the influence of microstructural parameters on the physical properties indirectly measured by an electromagnetic sensor has not yet been completely elucidated. The objective of the present work is thereby to understand the relations between microstructure, mechanical properties, and electromagnetic behavior of carbon steel wires submitted to different thermomechanical treatments. It aims also at improving the knowledge of the physical and mechanical metallurgy of these steels. The effect of microstructure and plastic deformation on the electromagnetic responses of different steels with various tensile strengths was investigated through resistivity down to 2 K and magnetic measurements, as well as by ECT. In addition, magnetic domains could be imaged by magnetic force microscopy despite the complex microstructures. The electromagnetic responses changed according to the electrical conductivity and magnetic permeability variations of each material, which were mainly related to changes in the volume fraction, distribution, and morphology of the cementite phase within the α-ferrite matrix. The increase of carbon concentration enhances the localization of electrons at the atomic sites, assisting the covalent character of interatomic bonds and thereby reducing the conductivity of steels. Besides, the α-Fe3C interfaces that act as a physical barrier for dislocation slip in ferrite, affecting as well the main free-path for conductive electrons and magnetic domain walls displacements within the material. Conductivity and permeability increased in the order of martensite, sorbite, pearlite, proeutectoid ferrite-pearlite, spheroidite, and ferrite microstructures. Also, the electrical and magnetic behavior of fully pearlitic steels was observed to depend on the deformation resulted from the cold-drawing and in-service application where fatigue may occur. Low-cycle fatigue experiments have pointed out that the resistance can be managed by relevant thermo-mechanical treatments. The potentiality of ECT was highlighted as a characterization tool of the microstructural state and mechanical properties of steel wires during manufacturing processes or in-service environment. Finally, this technique has been shown to be useful for monitoring cyclic elastic deformation and plastic accommodation of pearlitic steels responding to fatigue-loading conditions

Low carbon micro-alloyed steels produce today a lot of metallic materials having high level of potentialities because of the possibility to use an elaboration processing more economic in association with interesting mechanical properties. Especially ' such steels have high mechanical strength coupled with a high toughness and a low brittle/ductile transition temperature. Our study has consisted in approach of characterization at two levels: - First one is a micro structural characterization by using of optical microscopy, scanning electron microscopy, transmission electron microscopy and microanalysis devices. - the second corresponds to a mechanical testing investigation such as tensile test, Charpy-V or U-notched test, BDWTT test, nano-hardness. The finality of these investigations has to carry out the correlation between the varied types of “bainitic” microstructures and the mechanical properties. The mixing of the bill type bainite and the tempered martensite provides the better compromise between the requirements asked for applications. However, this compromise is accessible only with the contribution of the micro-alloyed elements, which originate a precipitation under the form of the carbonitrides. These last contribute to the grain refinement in steels. This condition is absolutely necessary in order to have a high level of mechanical properties

This work deals with the synthesis, the physico-chemical and mechanical caracterisation of coatings obtained by cathodic magnetron sputtering of a metallic austenitic stainless steel target in different argon - reactive gas (nitrogen, methan or oxygen) mixtures. The metastable solid solutions which are nitrogen, carbon or oxygen supersatured, as weIl as the ceramic compound of oxide type (Fe, Cr, Ni)₃O₄, with their different crystalline or amorphous structures are studied by means of the main diffraction techniques of structural analysis and physical methods of chemical analysis. The second part of this work aims to point out the complete mechanical properties of the different coatings and composite (coating + substrat). The intrinsic properties of the different coatings were first studied in relation with the elaboration parameters and structural properties. Vickers indentation as well as single pass and triboscopic multipass scratch testing were then performed on the three type of N, C, 0 doped coatings, in order to establish a relation between the brittleness or ductility and the tribological behaviour (friction, wear)

: Pearlitic steels could appear to be a simple and classic microstructure, with a rather simple eutectoid composition containing twophases (cementite and ferrite) in a lamellar distribution. However, they feature a hierarchical microstructure, which is composed of nodulesthat present the same crystallography and are grain-equivalent, then the nodules comprise the colonies that contain the parallel ferrite andcementite lamellas at a nanometric scale. As a result, pearlitic steels offer high strength and ductility at a reasonable cost, which fits verywell for various structural and reinforcement applications, e.g., steel core, bridge cables, wire ropes, springs…Although pearlitic steels areknown and vastly studied for over 150 years, it could appear outrageous to still propose manners of improving their mechanical properties.However, some options have not yet been considered such as the microstructural gradient or the control of the pearlite morphologies. Themicrostructural gradient concept has been widely explored in simple microstructure in steels, such as ferrite or austenite, but it is morecomplicated to export it in the pearlitic steel. The present Ph.D. aims to investigate the feasibility of producing a microstructural gradient infully pearlitic steels and of controlling the pearlite morphology. It is sought the understanding of the involved metallurgical mechanisms andthe impact on the mechanical properties, especially fatigue, considering the final application of this material. The control of themicrostructure and the gradient is based on the transformation of austenite into pearlite and, therefore, all the parameters that couldinfluence this transformation must be studied. It includes heat treatment parameters (heating rates, cooling rates, cooling modes,temperature of transformation…) and materials ones (initial interlamellar spacing, deformation state of pearlite…). The spacing between theferrite and cementite lamella, known to govern the mechanical properties of pearlitic steels, varies with the transformation temperature,which results in coarse and fine pearlite when transformed at high or low temperatures, respectively. It is found that a microstructuralgradient of interlamellar spacing is possible to be formed but is limited by the rod diameter. Using the dilatometer, it was successfullyprocessed in a 6 and 12 mm diameter rod. The gradient-containing wires were then drawn and the mechanical properties before and afterdrawing are compared to assure that the gradients formed during the heat treatment of the 6 mm diameter wires are still present on the2.25 mm final diameter wires. The morphology of pearlite has also been modified by control of heat treatments using continuous andisotherm cooling. Divorced, connected and well-aligned perfect pearlites with the same interlamellar distance have been processed. It turnsout that the morphology of the monolithic pearlite specimen has a higher impact on cyclic plasticity than the presence of a gradient. Theresults obtained in this Ph.D. gave rise to discussions on the pearlitic transformation under continuous and isotherm cooling, on themechanisms controlling the morphology of pearlite (mostly divorced or lamellar), on the phenomena happening during heating,(recrystallization, recovery, and spheroidization), and also on the mechanisms of plasticity of pearlite. Finally, the feasibility of the productionof the gradients by real cooling technologies is assessed by transforming the wires in a pilot line. It is of most interest that the gradients areproduced by alternative cooling technologies since the lead patenting technique is not the most environmentally friendly, although the mostwidely used

The aim of this study is to understand and to model, on physical bases, metallurgical and mechanical phenomena that induce changes in crystallographic textures. Microscopic and textural characterizations have been performed on an IF steel during its industrial process: in the hot band state, then after cold rolling and finally after recrystallisation. Deformation heterogeneities characterization like the modeling has been realized at different scales. The parameters extracted from experimental work, allow an estimation of the fragmentation that occurs in some specific crystallographic orientations. These results are in accordance with the stored energy estimation realized by XRD with, in average, two times more energy in the γ-fibre grains than in the α-fibre grains after high cold-rolling levels, but with low differences for low thickness reductions. A hierarchy of the fragmentation F is proposed such as F{100}<110> < F{112}<110> < F{111}<110> < F{111}<112> < F{554}<225>

We have studied the structural behavior of a stainless steel capable of age hardening, with a very low carbon content. The martensitic alloy concerned by this research has the following composition : Fe-11. 7 Cr-9. 2 Ni-1. 99 Mo-0. 71 Al-0. 34Ti. The thermal treatments have been undertaken in the temperature range of -160°C and 1150°C. The kinetics of the austenitic transformation and the volumic fraction of reversed austenite stabilizes at ambient temperature have been caracterized as a function of the treatment conditions (isothermal and/or isochronal). During isothermal tempering three stages of hardening may occure before the overaging phenomenon and the formation of reversed austenite. Finally, interesting mechanical properties (Rm and R0. 002) and the improvement of A % and KCV for this alloy, can be obtained when the tempering is performed in the range of 525-550°C, the increase in ductility and toughness being obtained to the detriment of a small decrease in mechanical proof
