The ExoMet proposal revolves around innovative liquid metal engineering and the application of external physical fields, in order to significantly influence the microstructures and properties of light alloys, such as aluminium and magnesium. Three types of external fields will be explored, namely: electromagnetic, ultrasonic and intensive mechanical shearing. To meet the future EU challenges of lightweighting and pollution reduction, especially relevant in transportation, it is necessary to improve the castability of light alloys, to enhance grain and eutectic refinement in monolithic alloys, and to develop new high-strength nanocomposites using nano-reinforcers which have only recently become available. Significant mechanical property improvements are foreseen in ExoMet - including 50% increases in tensile strength and ductility, as well as creep resistance up to 300-350 degC (currently limited to about 200 degC in Al and Mg alloys). This applies to both shape castings and wrought products like extruded profiles, bar, cable, sheet and plate. Manufacturing scale-up will be tackled in ExoMet, using a variety of techniques such as low and high-pressure die casting, sand casting, investment casting, differential-presssure casting, twin-roll casting, ultrasound-assisted casting and twin-shear casting. The application of external fields to these industrial techniques is novel and would bring about major savings in energy, scrap and processing cost. Having developed the field-enabled processes and produced high-quality light alloys and nanocomposites, the next stage of ExoMet will be prototypying and the assessment of industrial applications in four selected commercial sectors: (i) automotive powertrain and chassis, (ii) aircraft and aero-engine structures, (iii) space satellite and rockets, and (iv) high-strength high-conductivity Al electrical cabling. Computer modelling, rig-testing, standardisation, life-cycle analysis and patenting will also be undertaken.

This invention relates to a method for decontaminating radioactively contaminated material, for example construction waste. The material is comminuted by means of voltage pulses and can be divided with a high degree of selectivity into non-contaminated or only weakly contaminated material and contaminated remainder. The majority therefore represents non-contaminated or only weakly contaminated waste material which can be disposed of much more easily than the contaminated remainder. Therefore, the method is particularly suitable for reducing the volume of radioactive waste material which is subject to stringent safety requirements in respect of its storage and disposal and therefore its storage and disposal incur high costs.

An apparatus for coating substrates with a coating material is disclosed. The apparatus includes a frame and a crucible arrangement including a first crucible and a second crucible disposed on the frame. Only one first shaft is associated with the first crucible and only one second shaft is associated with the second crucible, where the only one first and second shafts are disposed in the frame beneath the first and second crucibles, respectively. Only one first lifting device is associated with the only one first shaft and only one second lifting device is associated with the only one second shaft, where the only one first and second lifting devices are disposed in the frame. The only one first and second shafts and the only one first and second lifting devices are laterally displaceable with the frame.

A remelting furnace is disclosed. An electrode rod drive with an electrode rod, as well as a retaining ring to retain a high-current cable, are arranged on a platform which is located on a weighing cell. Even though the position of the high-current cable changes during lowering of the electrode rod supporting a consumable electrode, the recorded weight portion of the high-current cable remains the same, which means that ultimately the change in the weight of the consumable electrode can be determined with the weighing cell.
