Summary
High performance lead-free piezoelectrics based on polar nanoregions. This project aims to enhance the electro-mechanical couplings of lead free piezoelectrics via introducing polar nanoregions for medical transducers applications. This is expected to impact on the design and development of high-performance lead free piezoelectrics, and have environmental benefits through replacing lead based counterparts.

A Predictive Approach to the Formation of Plate-Shaped Strengthening and Toughening Constituents in Advanced Metallic and Ceramic Materials. Development of stronger and tougher materials has been largely empirical and the properties obtained so far are only a small fraction of the theoretical values. One of the key steps to develop stronger and tougher materials is to understand the mechanisms responsible for the formation and distribution of key strengthening and/or toughening components in the ....A Predictive Approach to the Formation of Plate-Shaped Strengthening and Toughening Constituents in Advanced Metallic and Ceramic Materials. Development of stronger and tougher materials has been largely empirical and the properties obtained so far are only a small fraction of the theoretical values. One of the key steps to develop stronger and tougher materials is to understand the mechanisms responsible for the formation and distribution of key strengthening and/or toughening components in the materials. This project seeks to make this step. The findings will provide guidance to the development of stronger and tougher materials for the aerospace, aircraft and automotive industries. This project provides opportunities to strengthen the collaboration with USA experts and to train early career researchers.Read moreRead less

Legislation against the use of lead initiated a search for lead-free piezoelectric ceramics. This project aims to derive guidelines for the development and implementation of this new class of materials. This project will utilise an analysis technique that allows elucidation of the origin of the high strain in piezoelectric materials. A separate analysis of the three known strain mechanisms in materials with coexisting phases will innovatively correlate theory and macroscopic observation with processes on the atomic scale. The quantification of the contribution of each mechanism will lead to new insights into the enhancement of sustainable functional materials.Read moreRead less

Enhanced electro-active properties in polycrystalline ceramics: a multi-length-scale approach. Electro-active materials are used in a wide range of devices including ultrasound imaging equipment and nano-positioning systems. This project will determine the most fundamental mechanisms at work in these materials allowing for the optimisation of high-performance and environmentally friendly electro-active devices for future industries.
Grain-boundary sliding in high-temperature ceramics: mechanical spectroscopy of high-purity magnesium oxide. The demise of elastic behaviour in materials stressed at sufficiently high temperature limits the usefulness of ceramics for structural applications, and is also responsible for reduced wave speeds and associated attenuation of seismic waves in the Earth's interior. Yet the nature of the transition in fine-grained materials tested at high temperature from elastic through anelastic to vis ....Grain-boundary sliding in high-temperature ceramics: mechanical spectroscopy of high-purity magnesium oxide. The demise of elastic behaviour in materials stressed at sufficiently high temperature limits the usefulness of ceramics for structural applications, and is also responsible for reduced wave speeds and associated attenuation of seismic waves in the Earth's interior. Yet the nature of the transition in fine-grained materials tested at high temperature from elastic through anelastic to viscous rheology remains poorly understood. Through a combination of mechanical testing by torsional forced oscillation/ microcreep methods of carefully fabricated and characterised specimens of polycrystalline MgO and associated micro-mechanical modelling we seek to clarify this fundamental and general aspect of high-temperature mechanical behaviour.Read moreRead less

Summary
Fatigue degradation in lead-free piezoelectric ceramics: the key factor for successful industrial implementation. Many everyday devices, that is mobile phones, operate with lead-based ceramics, which can be hazardous; although there are promising lead-free materials, these show complex electric behaviour which can lead to structural damage and device failure. This project will define the degradation mechanisms so that reliable non-toxic ceramics can be designed.
