This project will initiate and establish a collaborative research program between Professor Wojciech Z. Misiolek of Lehigh University (Bethlehem, PA, USA) and Professor Graham Schaffer at The University of Queensland. Professor Misiolek will spend an extended six month period at The University of Queensland. The specific aim of the project is to develop a method to machine aluminium composites in the green, or unsintered, state. This will overcome a major impediment to the wider utilisation of aluminium matrix composites, which have an attractive combination of properties but cannot be formed into complex shapes using conventional processing methodologies.Read moreRead less
Development of Creep Resistant TiAl Alloys for High Temperature Structural Applications. TiAl based alloys are being developed as high temperature structural materials for aerospace and automotive applications and thus their creep resistance (long-term strength at elevated temperatures) is critical. This project aims at developing creep resistant TiAl alloys through a combination of addition of rare earth and severe plastic deformation. It is expected that a refined and stablised microstructure ....Development of Creep Resistant TiAl Alloys for High Temperature Structural Applications. TiAl based alloys are being developed as high temperature structural materials for aerospace and automotive applications and thus their creep resistance (long-term strength at elevated temperatures) is critical. This project aims at developing creep resistant TiAl alloys through a combination of addition of rare earth and severe plastic deformation. It is expected that a refined and stablised microstructure consisting of submicron lamellar grains and nanosized lamellae be obtained. This will result in a highly creep resistant prototype TiAl material and leads eventually to the development of commercial TiAl alloys.Read moreRead less
Testing, modelling and engineering applications of topologically interlocking structures. The CI and his international collaborator have recently proposed a new principle of design of materials and structures based on topological interlocking of constituent elements.

Unusual properties, such as high fracture toughness and damage tolerance were found. The project a ....Testing, modelling and engineering applications of topologically interlocking structures. The CI and his international collaborator have recently proposed a new principle of design of materials and structures based on topological interlocking of constituent elements. Elements of simple shape, such as tetrahedra, are assembled in structures that keep their integrity without any binder or connectors. Unusual properties, such as high fracture toughness and damage tolerance were found. The project aims at investigating the mechanical and acoustic properties of the newly discovered interlockable geometries (cubes, octahedra, dodecahedra and icosahedra) and identifying the areas of application. The project will promote the international leading role of the collaborating institutions in this novel field.Read moreRead less
Damage micromechanisms in alumina hybrid bilayers with graded interfaces. This project proposes a new design concept for high performance alumina hybrids with graded interfaces. The key to this process is the incorporation of thin graded interfaces between an outer homogeneous alumina layer for strength, hardness and wear resistance, and an inner heterogeneous alumina hybrid layer for damage tolerance. The project will explore unresolved issues concerning the effect of graded interfaces on the f ....Damage micromechanisms in alumina hybrid bilayers with graded interfaces.
