Original Abstract

The aim of the work was to describe effect of long-term ageing on the microstructure and fracture properties of the Eurofer97 steel. The embrittlement of the high chromium ferritic-martensitic implies important limitation for use of these steels [1] caused carbide coarsening and/or intercrystalline embrittlement [2]. Detailed microstructure studies were carried out on the steel in as-received state and in state after long-term thermal ageing for 550 stupňů Celsia ,5.000 h. Mechanical properties were evaluated by means of Charpy impact testing. Only a slight growth of the particles and partial recrystallization of the subgrains after thermal ageing has been observed. The isothermal ageing caused shift in tDBTT about +5 stupňů Celsia Degradation of the impact properties was probably caused by synergic effect of carbide coarsening and mind recrystallization of the subgrains.
