Original abstract
The ferritic-martensitic reduced activation steel Eurofer97 is candidate structural material for in-vessel components of proposed fusion reactors. The embrittlement of the high-chromium ferritic-martensitic steels implies important limitation for use of these materials. The microstructure and fracture properties of the Eurofer97 steel sheets of thickness 25 mm were investigated in as-received state and in state after long-time thermal ageing (550 C/5.000 h/air). Detailed microstructure studies were carried out by means of optical, electron and quantitative electron microscopy in as-received state and in state after long-time thermal ageing. Mechanical properties were evaluated in both states by means of Charpy impact testing. The microstructure of the Eurofer97 consisted of tempered martensite with M23C6 and MX precipitates. The isothermal ageing caused evident shift in tDBTT about +5 C, no proofs of embrittlement were observed on fracture surfaces
