Anisotropy of strengthening by solid solution and precipitation in concentrated Mg-Al and Mg-Zn alloys. The addition of solute increases the strength of Mg in some crystallographic directions but weakens the material in others. The weakening is called solid solution softening, and it can have profound effects on the mechanical behaviour of the material. Solid solution softening has been observed in the prismatic planes of single crystals of dilute Mg-Al and Mg-Zn alloys.

The addition of solute increases the strength of Mg in some crystallographic directions but weakens the material in others. The weakening is called solid solution softening, and it can have profound effects on the mechanical behaviour of the material. Solid solution softening has been observed in the prismatic planes of single crystals of dilute Mg-Al and Mg-Zn alloys. Easier prismatic slip lowers the strain hardening rate and increases the ductility of polycrystalline alloys in comparison with pure Mg. Despite their obvious significance, these effects have not been studied in single crystals of concentrated alloys. This is the main object of this project.Read moreRead less

Structural materials are the basic building blocks of modern society, even a small advancement can have a strong impact on our society. The properties of steel have been pushed close to the limit. The development of bulk metallic glasses (BMGs) offers the opportunity to revolutionize the field of structural materials with strengths 3 or 4 time that of steel. The proposed project, aims to overcome the major technical barrier for BMGs of insufficient ductility. The development of ductile and high strength BMGs, will position Australia and its researchers at the forefront of this exciting material innovation. The project will develop and strengthen Australia's international research linkages with overseas centres of excellence.Read moreRead less

The work has the potential for very substantial benefit to Australia. Novel stress corrosion cracking resistant tempers with improved strength have the potential for widespread application in the aircraft industry. Since the patent for the interrupted ageing process is held by CSIRO there is the potential for substantial economic benefit to Australia from the licensing of the novel tempers world-wide. Additionally, it would be possible to develop the novel tempers in-situ on existing aircraft structures to improve their performance. This would be of particular benefit to the Royal Australian Airforce with its fleet of ageing aircraft.Read moreRead less

Giant magnetic hardening in flash-annealed nanocomposite magnets. One of the most important properties required for permanent magnets is the coercivity. Recent results from an international collaboration between the Chief Investigator and researchers from the Japanese materials industry have shown that rapid heating can enhance the coercivity of chromium-added iron-neodymium-boron-based nanocomposite magnets by 30 times. The aim of this project is to clarify the mechanism of this giant magnetic ....Giant magnetic hardening in flash-annealed nanocomposite magnets.

Recent results from an international collaboration between the Chief Investigator and researchers from the Japanese materials industry have shown that rapid heating can enhance the coercivity of chromium-added iron-neodymium-boron-based nanocomposite magnets by 30 times. The aim of this project is to clarify the mechanism of this giant magnetic hardening effect and thereby establish a basis for further development of economically viable nanocomposite magnets with low neodymium content. Our novel flash-annealing process will allow exploration of new nanocomposite alloys, which may lead to Australian-owned patents.Read moreRead less
