This project aims are to achieve a fundamental understanding of the fatigue behaviour of lead-free piezoelectric ceramics which achieve high strain through phase transformations and then ascertain the effects of this behaviour on material degradation rates. The expected outcomes will facilitate replacement of toxic lead in commodity electronics. The focus will be on new lead-free bismuth-alkali-based piezoelectric ceramic systems which demonstrate exciting potential as alternate materials to lead zirconate titanate (PZT) materials. Successful optimisation of the materials' design and knowledge of their degradation rates are expected to facilitate their commercialisation through a profound reduction in the environmental challenges associated with manufacture and disposal of devices.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

This project aims to develop new processing techniques to accelerate the formation of low temperature intermetallic compounds. Many exciting compounds cannot currently be used in technological applications, as they would require extremely protracted heat treatments to produce. The project will aim to determine if formation of these compounds will be accelerated if the precursor alloys are mechanically disordered so that they contain a very high density of defects. This problem will be explored by investigating the formation of prototypical materials including ferromagnetic and precious metal intermetallic compounds from disordered precursors. The project will result in improved strategies for manufacturing intermetallic compounds.Read moreRead less
