Summary
Microstructure design of second generation MgB2 superconducting wires for enhancement of critical current density. Magnesium diboride (MgB2) superconducting wires have outstanding potential for a diverse range of commercial applications. However, the critical current density in MgB2 wires is still comparatively low, which represents the biggest obstacle in terms of their practical applications. This project will further enhance the critical current density in second generation MgB2 wires prepare ....Microstructure design of second generation MgB2 superconducting wires for enhancement of critical current density. Magnesium diboride (MgB2) superconducting wires have outstanding potential for a diverse range of commercial applications. However, the critical current density in MgB2 wires is still comparatively low, which represents the biggest obstacle in terms of their practical applications. This project will further enhance the critical current density in second generation MgB2 wires prepared by an optimised internal magnesium diffusion process through addressing fundamental issues and designing appropriate microstructure. The research outcomes will be extremely beneficial to fundamental research and to the potential application of MgB2 superconductors. High-performing, low-cost second generation MgB2 wires are also expected to be developed in this project.Read moreRead less

Summary
Advanced X-ray diffraction facility for high energy and extreme conditions. X-ray powder diffraction is a powerful technique for determining the structure of matter at the atomic scale. This project will establish a new Australian capability for X-ray powder diffraction under extreme conditions that emulate real harsh service environments for advanced functional materials.
Development of a solid nitrogen cooled magnesium diboride (MgB2) magnet for persistent-mode operation. Soaring price for liquid helium has increased demand for cryogen-free superconducting magnets more than ever. If magnetic resonance imaging magnets, which represent over 50 per cent of the world superconducting markets, could be operated without liquid helium, magnetic resonance imaging would be much more affordable and enable reduced health care costs.
Core loss mechanisms in soft magnetic nanostructures. This project aims to clarify the mechanism of power losses in magnetic cores used in the petrol-electric hybrid cars by investigating the relationship between the core losses and magnetic correlation lengths in iron alloys. This project expects to generate new knowledge on the effect of magneto-mechanical interaction on the anomalous core loss in iron based alloys. The intended outcomes include an experimental confirmation of the random aniso ....Core loss mechanisms in soft magnetic nanostructures. This project aims to clarify the mechanism of power losses in magnetic cores used in the petrol-electric hybrid cars by investigating the relationship between the core losses and magnetic correlation lengths in iron alloys. This project expects to generate new knowledge on the effect of magneto-mechanical interaction on the anomalous core loss in iron based alloys. The intended outcomes include an experimental confirmation of the random anisotropy model, a major theoretical model in nanostructured materials and identification of ideal magnetic domain configurations for lower power losses. These intended outcomes should bring great benefits to the development of low-carbon vehicle technologies for sustainable motorisation in Australia.Read moreRead less
Nanostructured soft magnetic alloys for low-carbon cars. The aim of this project is to prepare iron-based magnetic nanostructures that exhibit a magnetic induction of 1.9 tesla and core losses lower than those of iron-silicon steels, which would deliver smaller and efficient magnetic cores for petrol-electric hybrid cars. Preliminary results from the research team show that iron-metalloid alloys with an iron content of 87 per cent meet this magnetic induction with room for further improvement of ....Nanostructured soft magnetic alloys for low-carbon cars. The aim of this project is to prepare iron-based magnetic nanostructures that exhibit a magnetic induction of 1.9 tesla and core losses lower than those of iron-silicon steels, which would deliver smaller and efficient magnetic cores for petrol-electric hybrid cars. Preliminary results from the research team show that iron-metalloid alloys with an iron content of 87 per cent meet this magnetic induction with room for further improvement of magnetic softness. The project aims to systematically investigate the effect of metalloid and micro-alloying elements on the nano-crystallisation behaviour of the precursor amorphous alloys in order to identify the alloy composition and processing conditions for preparing magnetically soft nanostructures.Read moreRead less
Soft magnetic nanostructures for clean automotive technologies: origin of induced magnetic anisotropies. This project will clarify the mechanism of annealing-induced magnetic anisotropies in magnetic nanostructures and thereby establish a basis for further alloy development of efficient core materials for electric motors.
