Segregation at grain boundary in YSZ
In practical ceramics and metallic materials, different elements are often added to improve the properties. In such cases, the added elements segregate at the grain boundaries and have a significant effect on the properties of the material. I am observing and analysing the segregation structure of grain boundaries at the atomic level using STEM with the aim of elucidating the mechanism of this grain boundary segregation phenomenon.
