Unravelling the structural origin of cyclic fatigue in ferroelectrics. Ferroelectric materials have extensive applications in electromechanical devices and memories and in service are often subjected to repeat mechanical and/or electrical loading, leading to cyclic fatigue and failure.

Ferroelectric materials have extensive applications in electromechanical devices and memories and in service are often subjected to repeat mechanical and/or electrical loading, leading to cyclic fatigue and failure. This project aims to apply in-situ electron microscopy techniques and computational modelling to explore cyclic ferroelectric fatigue behaviour and to understand the relationships between local atomic scale structure and fatigue. The structural origin of ferroelectric fatigue has not been clear because of the limitations of previous measurement capabilities. This project will provide guidance in materials design to increase ferroelectric fatigue lifetime for more reliable ferroelectric-based electronic devices.Read moreRead less

This project aims to study grain boundaries, which are important in the mechanical behaviour of nanomaterials. However, the exact contribution of individual grain boundaries to mechanical properties is not well understood, affecting advanced materials design. This project will use in-situ deformation transmission electron microscopy techniques to reveal how individual grain boundaries deform and interact with dislocations, and to link directly the structures and orientation of individual grain boundaries with mechanical behaviours. Expected results are better structural design of advanced metallic nanomaterials with superior mechanical performance.Read moreRead less

Summary
Probing the nanomechanics of single grain boundary with decorated solutes. Grain boundaries (GBs) are thermodynamically susceptible to attract solutes to reduce system energy. Elaborately manipulating the GB nanostructure and chemistry via segregation can essentially be conducive, rather than detrimental, to materials performance. However, the underlying mechanism of GB segregation and its detailed effect on material properties remain elusive due to the GB complexities in the polycrystals.

Elaborately manipulating the GB nanostructure and chemistry via segregation can essentially be conducive, rather than detrimental, to materials performance. However, the underlying mechanism of GB segregation and its detailed effect on material properties remain elusive due to the GB complexities in the polycrystals. Through correlative in-situ nanomechanical testing and atom probe tomography, this project aims to unravel the rationale of segregation behaviour of individual GBs and its effectiveness to enhance the material performance, and hence enable nanostructural design of advanced metallic materials with unprecedented properties.Read moreRead less
