Original abstract
The aim of the work was to describe effect of long-time thermal ageing on the microstructure and fracture properties of the Eurofer97 steel. The ferritic-martensitic reduced activation steel Eurofer97 is candidate structural material for in-core components of proposed fusion reactors. The embrittlement of the high-chromium ferritic-martensitic steels implies important limitation for use of these materials. Properties of the Eurofer97 steel were investigated in as-received state and in state after long-time thermal ageing. Isothermal ageing (550 C/5.000 h) was applied to partially simulate service condition in ITER.
Czech abstract
Cílem práce bylo popsat vliv dlouhodobého tepepného žíhání na mikrostrukturu a lomové vlastnosti oceli Eurofer97. Feriticko-martenzitická RAFM ocel Eurofer97 je kandidátní konstrukční materiál pro jádrové komponenty navrhovaných fůzních reaktorů. Zkřehnutí vysoko chromových ocelí způsobuje významné omezení při použití těchto materálů. Vlastnosti oceli eurofer9 byly zkomány v dodaném stavu a ve stavu po dlouhodobém žíhání. Izotermické žíhání (550 C/5.000h) bylo aplikovano aby částečně simulovalo provozní podmínky v ITER.
