Dislocation motion and anelastic recovery in layered ceramic titanate

本项目旨在研究脆性陶瓷纳米线材料的变形和制备以及拉伸变形中的滞弹性行为。层状钛酸钠被用于储能和水处理，但原位拉伸试验观察到了非常规变形行为，具有显著的位错运动和滞弹性恢复。本项目将通过分子动力学模拟、经验原子间势和原位透射电子显微镜实验来研究层状钛酸钠纳米线的变形机制。预期的成果包括了解这种层状钛酸盐的变形机制，这可以扩大到具有重要技术意义的层状陶瓷材料。

This project aims to research deformation and facture in brittle ceramic nanowire materials and anelastic behaviour in tensile deformation. Layered sodium titanate is used in energy storage and water treatment, but in-situ tensile tests have observed unconventional deformation behaviour, with significant dislocation motion and anelastic recovery. This project will study the deformation mechanism in layered sodium titanate nanowires through molecular dynamics simulations, empirical interatomic potential, and in situ TEM experiments. Expected outcomes include knowledge of the deformation mechanism of this layered titanate which can be broadened to technologically important layered ceramic materials.
