This project aims to design and fabricate superior eco-friendly substitutions for lead-based perovskites widely used in piezoelectric devices, to address the long-standing toxic concern of lead for human beings and the environment in the community. It is expected to surmount the fundamental limit of current approaches to reach giant room-temperature piezoelectric responses in lead-free perovskites through using a pioneering route named rare-earth doped relaxor/morphotropic phase boundary crossover. Success of this project will not only meet the Australia’s ecological sustainability goals, but also provide commercial opportunities for Australia in the large market of piezoelectric devices (> 25 Billion USD annually).Read moreRead less

Crack Propagation within Graded Interfaces. Functionally graded interfaces are a technologically new way of joining materials in a wide range of biomedical and industrial applications. The reduction in the interfacial stresses resulting from the graded interface increases the structural integrity of the component, however, existing models do not fully address issues of plasticity and cyclic fatigue to their fracture. The intention of this study is to investigate how modifications to the ductil ....Crack Propagation within Graded Interfaces. Functionally graded interfaces are a technologically new way of joining materials in a wide range of biomedical and industrial applications. The reduction in the interfacial stresses resulting from the graded interface increases the structural integrity of the component, however, existing models do not fully address issues of plasticity and cyclic fatigue to their fracture. The intention of this study is to investigate how modifications to the ductile reinforcement phase and how the cyclic loading influence crack extension within a graded interface. These results will assist in future design and prediction of the in-service lifetime of components containing gradient interfaces.Read moreRead less

Ti3SiC2 belongs to a large group of ternary carbides that exhibit an unique combination of high temperature ceramic properties, with the electrical and thermal conductivity of metals. A great number of potential applications have been identified, but are currently limited by residual intermediate compounds, that degrade the properties. This project will use crystal structure similarities between TiCx and Ti3SiC2 to engineer a crystalline precursor, Ti3C2, which circumvents intermediate compound formation. This innovative methodology will also reduce the cost and time of fabrication. Advanced in-situ neutron diffraction techniques will be used to quantify the synthesis kinetics and optimize the method.Read moreRead less
