Materials Research in Space, using magnetic fieldsOlivier Minster (European Space Agency)Materials research in space aims to consolidate the understanding of the relationship between materials processing, materials microstructure and materials properties. Owing to the conditions of weightlessness that prevail onboard orbiting spacecraft, the range of processing conditions that can be applied to metallic materials can be broadened. The accurate control of these conditions includes the utilisation of magnetic fields that enable scientists to induce precisely defined convective conditions. Furthermore, the utilisation of magnetic fields permits to hold, thermally control and manipulate metallic samples without contact and thereby to investigate their thermophysical properties as well as their solidification features. MHD in Hall Heroult processOlivier Martin (RioTinto-ALCAN, France)After a short introduction about Aluminum Industry and Rio Tinto Alcan technology, the presentation describes the Aluminium cell, the cycle of development for a new Technology. In a second part, the impact of the magnetic field in the process is shown. The last development of MHD modelling and their impact on energy consumption reduction is detailed. Nanomaterials challenges in the field of renewable energyHélène Burlet (French Atomic Energy Centre, Grenoble)Many of the material challenges for the production, the storage, and the conversion of energy can be solved with the use of nanomaterials. A brief review of the potentiality of various nanomaterials such as nanowires, quantum dots, nanocomposites for batteries, photovoltaic devices, fuel cells and harvesting devices will be presented. Industrial application of electromagnetic devices for materials processingOla Widlund (ABB Corporate Research, Sweden)Magnetic fields have found wide-spread use in industrial materials processing, in particular in the steel industry.We present a review of some current applications, and an outlook on future challenges and opportunities for the industry. Status and prospects of electromagnetic actuators in steelmaking processesP. Gardin (ArcelorMittal, France)The presentation will concern the description of some electromagnetic actuators used in ArcelorMital Group, both for liquid metal, taking profit of Lorentz forces, and for strip when Joule heating is the topic. Because industrial implementation of such actuators requires a high level of knowledge and expertise, they will be a description of the different tools which are currently used for their design and evaluation, including mathematical modeling or experimental set-up. Positive effect of efficient collaboration with academic partners will also be described. Friday, March 27th Perspective on Magnetic Fusion Research, Development, and applicationsMohamed Abdou (UCLA, USA)Fusion promises to be the ultimate energy source for mankind, but the scientific and technological challenges are enormous. ITER, now being constructed in France is a major step in fusion research. But the most challenging stage of fusion development still lies ahead: the development of Fusion Nuclear Science and Technology (FNST). This stage will aim at developing the nuclear components surrounding the plasma, which are exposed to an extreme environment of high surface and volumetric heating, intense radiation fluxes, strong 3-component magnetic field, and many thermal/chemical/mechanical/electromagnetic interactions. The presence of these multi-function components in the unique and complex fusion environment leads to many new multi-physics, multi-scale phenomena and synergistic effects that require extensive worldwide R&D programs to understand and predict. Future Prospect of Electromagnetic Processing of MaterialsShigo Asai (JFE, Japan)The three combined fields of the magnetic field and laser, the magnetic field and micro-wave and the magnetic field and super-sonic wave are discussed in respect of the future prospect and desire of magneto science. The possibility of the magnetic orientation of crystals with an isotropy structure such as a cubic crystal is discussed and the utilization of an abnormal crystal growth is proposed. A new magnetic processing modifying the magnetic property of a substance is proposed. Electromagnetic Stirring (EMS) for Continuous Casting of Steel, achievements and prospectsSiebo Kunstreich (Danieli-Rotelec, France)The achievements of EMS are described as a product of R&D, opportunities and economic interests. EMS for long products can be considered as mature technology, EMS for flat products is still under progress. The latest developments are focussed on quantitative flow control of liquid steel in the mould of slab casters. The currently available methods and tools, theoretical and practical ones, are analysed and prospects for further R&D work are discussed. Investigation on solidification of metals under a strong magnetic fieldZhongming Ren (Shanghai University, China)A series of experiments have been carried out to investigate the influence of a strong magnetic field up to 12T on orientation and alignment of crystals, cellular and dendrite growth, lamella eutectic growth, migration of primary crystal during solidification of metals. It is shown that the strong magnetic field dramatically influences the solidification. Models are put out to explain the phenomena according to the effect of strong magnetic field and solidification theory. Measuring, Modelling, and Magnetic Control of Liquid Metal FlowsGunter Gerberth (Forschungzentrum Rossendorf, Germany)Based on a short review on velocity measurements examples are presented on the experimental modelling of metal and semiconductor melt flows, and the related control of those flows by steady or alternating magnetic fields. Examples will cover the aluminium investment casting, the continuous steel casting, and the Czochralski crystal growth. EPM Application to Environmental TechnologyShoji Taniguchi (Sendai University, Japan)It is strongly needed to change the present industrial technologies with high consumption of energy and resorces toward environment-friendly technologies to establish sustainable society. In the present talk, the author will show some applications of EPM to the production of new materials with low environmental load and waste treatment like asbestos containing waste and fly ash from coal power plant. Future applications of electromagnetic fields in industrial processesBernard Nacke (Hannover University, Germany)The use of electromagnetic fields in industrial processes (EPM) is still increasing in conventional industrial applications like melting, casting, forming and treatment. In future new areas in metal and non-metal industry will use EPM technologies in order to improve material quality or productivity. Growing areas will be especially in crystal growth of semiconductors and photovoltaic cells. Electromagnetic Flow MeasurementAndré Thess (Ilmenau Univ + DFG)Measuring the velocity in liquid metals is a notoriously difficult problem because these materials are opaque and often hot and aggressive. The goal of the present communication is twofold. First, we will provide an overview of the history of electromagnetic flow measurement starting from Michael Faraday's experiments in 1832. Second, we will describe a novel flow measurement technique termed Lorentz force velocimetry and discuss its potential applications an future research directions. Applications of magnetosciences to materials processing and energy: where are future ways?Yves Fautrelle (SIMAP, Grenoble) |
SCOPEGoalThe EPM group, part of the SIMAP laboratory, is organizing a seminar aimed at prospecting new research directions in Magnetosciences and their application to Energy and Material Processing. Background In 1976, during the Euromech Colloquium entitled “Where is MHD going?”, a new scientific area was foreseen at the crossroads of fluid mechanics, metallurgy and electromagnetism. In 1978, the MADYLAM Joint Research Program was launched in Grenoble to stimulate efforts in this interdisciplinary field. The MADYLAM Laboratory was officially founded in 1986, and its name changed to EPM (Electromagnetic Processing of Materials) in 1994, reflecting the internationally recognized label jointly proposed by Professor S. Asai in Japan and Doctor M. Garnier in France. In 2007, the EPM laboratory merged with other laboratories, becoming one of the six research groups of the new SIMAP (Sciences and Engineering for Materials and Processes) research division.
