The effects of neutron irradiation on austenitic stainless steels, usually used for the manufacturing of internal elements of nuclear reactors (e.g. the core shrouds), are the alteration of the microchemistry and the microstructure, and, as a consequence, ...
Modeling of the constitutive behavior was undertaken for Fe- Cr-C tempered martensitic alloys. Tensile tests were carried out at room temperature and constant nominal strain rate. In order to obtain a fully martensitic structure with different prior austen ...
A microstructural analysis and tensile tests were performed on two oxide dispersion strengthened ferritic/martensitic steels. Dispersion hardening represents an interesting approach to improve the mechanical properties at elevated temperatures, as they are ...
Considerable research work has been conducted on the ferritic/martensitic steels since the last International Conference on Fusion Reactor Materials in 1999. Since only a limited amount of that work can be reviewed in this paper, four areas will be emphasi ...
Neutron-irradiation-induced embrittlement of a 2.25Cr1Mo steel is investigated by means of small punch testing along with scanning electron trucroscopy. There is an apparent irradiation-induced embrittlement effect after the steel is irradiated at about 40 ...
Titanium alloys have been identified as candidate structural materials for the first wall, the blanket and the magnetic coil structures of fusion reactors. Titanium alloys are interesting materials because of their high specific strength and low elastic mo ...
Irradiation-induced embrittlement of a 2.25CrlMo is investigated by means of small punch testing and scanning electron microscopy (SEM). The ductile-brittle transition temperature (DBTT) determined by the small punch test is much lower than that determined ...
Within the "industrial architecture", the thesis is – in a general sense – the story of a travel in the space (from the Liguria sea – but not only – to the Valle dlAosta mountains), and in the time (the XXth century). The structure of the narration preview ...
Polycrystalline specimens of the ferritic-martensitic OPTIMAX A steel have been irradiated on the one hand with neutrons at 523 K to a dose of 2.5 dpa and with 590 MeV protons at ambient temperature and 523 K to doses of about 0.3 and 1 dpa on the other. C ...
The aim of this work is to examine the possibility of high performance pressure sensors based on piezoresistive thick films deposited on steel membranes, which combine the performance advantage of thin-film sensors (high-strength steel substrates, assembly ...
