Texto completoMaster of Science
The sensitization of stainless steel describes the process by which a high-carbon steel alloy is heated above a certain threshold (either naturally or artificially) followed by a cooling period during which chromium (one of the elements most responsible for providing stainless steel with its corrosion-inhibiting properties) forms new compounds with the carbon present in the steel. With the chromium being taken from the parent material to form these compounds, the corrosion-resistant properties are compromised, which can lead to corrosion, cracking, and broader failure. Currently, the accepted techniques used to test for the presence of sensitization are qualitative and/or destructive in nature. Attempts have been made to non-destructively detect and characterize sensitization through various means, but all with mixed results. With the use of these high-carbon alloys in a range of industries, a comprehensive, in-place process is desirable. This thesis will focus specifically on non-destructive evaluation of sensitization seen as a result of welding steel plates using induction infrared thermography (IIRT). This process uses an induction coil to generate heat within a sample whose resulting heat signature can then be detected with an infrared (IR) camera and analyzed. Previous IIRT experimental results have shown higher levels of heating in the HAZ when sensitization is present as it modifies the original microstructure of the material. New IIRT experiments have been conducted on both welded and unwelded 440C alloy samples to establish quantitative data on the heating profiles. These results (in conjunction with the appropriate experimental parameters) were then used to create a numerical model to replicate them. Despite some limitations in populating the model with accurate parameters, the results obtained were in good agreement with the experiments and provide a foundation for future work. Future work will focus on establishing a predictive tool that can detect and quantify the level of sensitization in an arbitrary steel sample in the field.

Texto completoThe economical and security aspects of the durability of the prestressed concrete construction works lead to develop new non destructive testing methods. This work was developed within the framework of the ANR ACTENA French research project. The main arms are to contribute to the localization of prestressed tendon ducts or rebars and also to the detection of the poor filling defects. The context of this study and previous works are described in the chapter I. The introduction of an inductor heating provides a non uniformity of the heating. In order to avoid any misinterpretation of thermograms, a frequential method based on transfer functions is proposed in chapter II. A 3D numerical model of the experimental specimens is performed by finite element method. Chapter III shows experimental results for three concrete beam specimens. The frequential procedure is applied to the raw thermograms. The results are discussed and highlighted the interest of phase images. A quantitative approach is applied to infrared thermographical results in the chapter IV. Finally, an inverse method is proposed and allowed to the determination of thermal diffusivity and the thickness of the cover concrete

Texto completoIn today’s competitive market, the quality control is vital in steelmaking industry where high quality product must pair with cost reduction. This control can be described as a system used for verifying and maintaining a desired level of quality. It implies careful inspection and corrective action if needed. The inspection can be performed with several Non-Destructive Testing (NDT) techniques to detect defects. Since the detection at the earliest possible stage is vital for the reduction of the quality cost, the ultrasonic systems have been used at pickling stage to detect internal defects without slowing down the production paces. However, there is still a need of a sensitive NDT technique to detect near subsurface defects which may turn into surface defects at downstream stages or even worse, at the customers during forming.Amongst the common NDT techniques, Active Infrared Thermography (AIRT) was identified as having a great potential for the detection of near surface internal defects. As an attractive NDT technique, AIRT has remarkable: it is contactless, relatively fast and versatile. Its principle is relatively simple: it consists in heating the sample and monitoring the surface response with an Infrared (IR) camera. The presence of any subsurface defect appears as specific thermal patterns in the recorded thermal sequence. Despite being an attractive technique, AIRT is not deployed yet to detect subsurface defects in steel strip at pickling stage on an industrial production line which is the innovative part of this thesis.The work provided in the thesis investigates the theoretical and experimental limits of AIRT for the detection of subsurface defects in steel samples. First, the investigation led to the development of laboratory tools capable of detecting near subsurface defects in static as well as moving samples. These developments are supported by 3D simulations which allowed evaluating the potential of the technique; gaining comprehensive knowledge; getting guidance for and/or optimize experimental designs. Then, the knowledge developed in laboratory has allowed outlining that the technique can be implemented directly in production line; especially at pickling stage where the strip travels at typically 5 m/s. Therefore, an inspection system was built and successfully implemented for the inspection of a reduced width of the moving strip in industrial environment. The thesis presents encouraging results and some keys identified points that should be considered for the design of full-integrated industrial AIRT inspection system

Texto completoThe non Destructive Testings are the active techniques which need an energy source to stimulate the specimen. The response is then analysed by an appropriate sensor to drive the internal state of the target. The hybrid techniques, combine two or several physical phenomena in order to have a good selectivity of the defect and to get more information about the target. In this work, we present a technique combining the electromagnetic and the thermal phenomena in conducting materials. In induction heating, the induced current and the temperature could be distributed at by the presence of the defect. This can be localised at the surface by an infrared sensor. The results may be analysed either by time evolution of the temperature or by its characteristics such as the phase or the amplitude in the case of sinusoidal excitation. Our contribution in this work is firstly the demonstration that the induction can stimulate the infrared NDT techniques. We develop then the 1D, 2D and 3D models to show the application domains of this technique. The results of the simulations are compared to experimental ones for a carbon fibre based composite shit

Texto completoThe work of this thesis deals with an innovative non-destructive testing (NDT) technique and its adaptation to the civil nuclear field. The numerical tool is used for this purpose. An exhaustive presentation of numerical models adapted to our problematic is made at first. These tools are then implemented and their performance compared. This made it possible to set up a fast digital tool capable of taking into account different modeling constraints such as circuit coupling, modeling of pronounced skineffect regions, as well as modeling of thin defects. This was followed by an experimental validation of the performances. Once the tool implemented and validated, it was exploited as part of a reliability assessment approach based on a MAPOD approach. In this context, an entire system for drawing input data and managing output data will be established. The result of this is a reliable and fast software tool dedicated to the evaluation of the sensibility of the thermoinductive technique

Texto completoAt different stages in the life cycle of the composite material, Non-Destructive Testing (NDT) methods are used to characterize its state of integrity. They play a vital role in the quality control and risk management. The main requirements of NDT are the ability to detect and discriminate defects of different types, precise dimensioning of defects, fast and reliable inspection and interpretation, and the ability to inspect structures of complex shapes. With regard to these requirements, composite materials of a very complex nature (heterogeneity, strong anisotropy and multi-layers) still pose problems for actual NDT methods. The work presented in this thesis is part of the European project NDTonAIR and deal with the development of a multi-physic and multi-scale modelling platform for the NDT of carbon fibers composite materials using eddy currents and induction thermography techniques. They aim to improve IREENA's 3D numerical software. The development of such simulation tools comes up against difficult modelling problems linked in particular to the complex nature of composite structures and the need to use high electromagnetic frequencies (up to a few MegaHertz) in order to induce sufficient power into these very low conducting materials. In previous work at IREENA, the simulation time was important, linked to the presence of massive conductors exposed to a high frequency electromagnetic field. It is in this context that we propose in this work, a 3D finite element method associated with surface impedance boundary condition with imposed current and voltage, in order to reduce the simulation times. The implemented simulation tools have been validated by comparisons with an analytical solution. They also make possible the design of a massive coil. The identification of the orientation of carbon fibers in a composite plate using eddy current technique is also investigated in this work

Texto completoEddy current thermography (ECT) is an active thermography method. The inductive excitation generates Eddy currents in electrically-conductive specimen. In a presence of defects, the eddy current flow is affected by these discontinuities leading to changes in the temperature distribution in the specimen around the defects. These changes are observed by an infrared camera. In this work, we present a robotic application of the method. A robotic interface is developed and all the sensors needed are integrated to the platform. Simulations are performed using COMSOL Multiphysics by varying different parameters. Experiments are realised on different specimens (made of different materials) with defects of different sizes. The linescan Eddy current thermography is studied and other modes are explored. The resulting images are reconstructed with a dedicated algorithm. Finally, the method’s results are compared to optical thermography to show the capability of the method.

Texto completoThanks to their excellent mechanical performance, the use of carbon fiber composites has been growing in recent decades. However, the large-scale development of these materials depends on the improvements of the processes during the various stages of their whole life cycle (eg. Producing, forming, assembly, inspection, recycling). At various stages of the life cycle of the material, nondestructive testing (NDT) methods can be used to characterize the health state of the material. They play a vital role in the quality control and risk management. Induction thermography NDT based on the measurement of thermal effect of the eddy currents in the material is a promising technique for this type of material. The development of this method requires multiphysics electromagnetic – thermal modeling. The model must deal with some numerical issues of thin regions of strong anisotropy. The implemented simulation tools allow reasonable computational time while retaining the desirable accuracy of numerical solutions. They are validated by comparisons with experimental measures. These tools allow accurate assessment of the performance of induction thermography technique
