| 英文摘要 | microstructural evolution in a ceo2-gd2o3 system at atomic and nanoscale levels with increasing gd concentration has been comprehensively investigated by transmission electron microscopy. when the gd concentration was increased from 10 to 80 at.%, the phase transformation from ceria with fluorite structure to solid solution with c-type structure was not a sudden change but an evolution in the sequence of clusters, domains, and precipitates with c-type structure in the fluorite-structured matrix. moreover, the ordering of aggregated gd cations and oxygen vacancies in these microstructural inhomogeneities developed continuously with increasing gd concentration. this microstructural evolution can be further described based on the development of defect clusters containing gd cations and oxygen vacancies. |
