dc.description.abstract铁电陶瓷材料在外场作用下电畴的反复翻转即畴变是引起材料结构变化,导致铁电材料性能衰退甚至破坏的主要原因。建立铁电陶瓷材料在外场作用下畴变的原位观测方法,对了解和掌握这类材料在外场作用下的失效机理、提高材料的使用寿命有重要的指导意义。本论文采用传统固相法,制备了晶粒分布均匀,平均晶粒尺寸23m、四方相结构的Pb(Zr0.52Ti0.48)O3和Pb0.93La0.07(Zr0.52Ti0.48)0.9825O3多晶陶瓷;设计和改造了适用于Raman散射光谱原位观测的四点弯曲应力加载装置并成功实现了与Raman散射仪的联用;运用Raman散射光谱技术,建立了对PZT...
dc.description.abstractDomain switching under an applied external field has been recognized as a fundamental origin causing deterioration and failure of the properties for ferroelectric ceramics. It is both theoretically and practically important to investigate the fatigue mechanism of ferroelectric materials by in-situ observation and measurement of domain switching behaviors under different loading conditions. In this...
