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

Development of ultrafine Grained Steels. This project will develop new methods to produce steels with much finer microstructures, and investigate how these microstructures form. This will markedly increase the strength and toughness of these steels, which is particularly required for the pipeline, off shore platform and large construction industries. The method to be used involves controlling the hot deformation of the steel and control of the phase transformation during or after deformation. ....Development of ultrafine Grained Steels.
