定量微结构与界面机理团队
【团队介绍】
“结构-性能”关系是材料研究与应用的基础,而多元化材料的微结构规律及调控是材料精细制备、功能协同优化的科学本质及应用发展的关键因素。我们对先进陶瓷材料、精细功能材料及新型能源材料与器件的微结构关系行为开展定量化、高精度、高通量的表征研究,探究微观、介观、宏观结构的多层次结构现象与规律,从源头掌握先进材料的“制备-结构-性能-服役”全链条研究、控制与行为预测。
【重点研究领域】
(1)高温结构陶瓷的相变微结构与极端条件下的高性能
(2)功能陶瓷、能源材料的复相规律与界面机理
(3)介观微结构电镜定量、高通量表征平台及自动化数据采集技术
(4)透射电镜精确表征及原位研究方法
