dcterms:description
Dlouhodobá expozice na teplotách 430oC a 650oC způsobuje zhoršení creepových vlastností niklové superslitiny EI 698 VD. Důvod degradace nebyl doposud vysvětlen. SANS, SEM a TEM metody pro výzkum mikrostruktury byly použity pro studium dlouhodobě exponované superslitiny EI 698 VD. Výsledky ukazují na významný vývoj mikrostruktury precipitátů s délkou expozice, což může mít za následek změnu mechanických vlastností materiálu. When exposed for long time at elevated temperatures of 430oC and 650oC the nickel-base superalloy EI 698 VD can experience a significant decrease in the creep. The cause of the creep degradation of nickel-base superalloy has never been unequivocally explained, but it has generally attributed to the microstructural instability at prolonged high temperature exposure. The creep lifetime decrease was more expressive as time of thermal exposure was extended up to 52 000 hours. In this article, the creep life data, generated on prior long thermally exposed wrought nickel-base superalloy were related to the microstructural changes observed using SEM and TEM analysing techniques.
