Description

The thermal behaviour of UO2 thin foils of (110), (001), and (111) orientation was observed by transmission electron microscopy using pulse beam heating. It is shown that the striations which appeared after such heat treatment represents facets elongated in 110 directions. A possible relation between faceting and surface reduction of UO2 is discussed

Abstract (German)

The thermal behaviour of UO2 thin foils of 〈110〉, 〈001〉, and 〈111〉 orientation was observed by transmission electron microscopy using pulse beam heating. It is shown that the striations which appeared after such heat treatment represent {111} facets elongated in 〈110〉 directions. A possible relation between faceting and surface reduction of UO2 is discussed. Dünne Plättchen von UO2 in 〈110〉-, 〈001〉- und 〈111〉-Orientierungen wurden mit starkem Elektronenstrahl bestrahlt und danach elektronenmikroskopisch untersucht. Es wird gezeigt, daß die durch Bestrahlung entstandenen Streifen in 〈110〉-Richtungen verlängerte {111}-Fazetten darstellen. Ein möglicher Zusammenhang zwischen der Fazettierung und der Oberflächenreduktion von UO2 wird erörtert.
