Thermal creep tests have been conducted on the EUROFER 97 reduced activation ferritic/martensitic (RAFM) steel and two kinds of oxide dispersion strengthened (ODS) EUROFER 97 steels, which were manufactured using slightly different powder metallurgy techni ...
An assessment of the true stress-true strain relationship has been done by means of tensile and small ball punch tests on austenitic and tempered martensitic steel at room temperature. A finite element model was developed and validated to calculate the for ...
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 ...
Angle-dispersive radial X-ray diffraction measurements were conducted on alpha- and epsilon-Fe under nonhydrostatic stress conditions up to 30 GPa and 1000 K in laser heated diamond anvil cells. alpha-Fe (bee) is found to develop preferred orientation comp ...
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 ...
The microstructure and tensile behavior of pure single crystalline Ni irradiated with 590 MeV protons are investigated. First results have been obtained for a damage level of 0.13 dpa at room temperature and 0.002 dpa at 523 K. The irradiation induced defe ...
The ball punch test technique was used to evaluate the conventional tensile and impact properties of the tempered martensitic steel EUROFER97 from room temperature down to liquid nitrogen temperature. The testing was carried out on unirradiated material on ...
The differences and similarities of behaviour between fee and bcc metals after irradiation have been investigated. For this purpose, fee Cu, Pd and 304 stainless steel and bcc Fe, Mo and Mo-5% Re were irradiated with either neutrons or 590 MeV protons at t ...
Tensile properties and microstructure of Danocrystalline electrodeposited Ni at temperatures between room temperature and 330° C are presented. Above 300° C low flow stress and high tensile elongation are observed along with grain growth and segreg ...
A new procedure of X-ray line profile analysis based on the dislocation model of strain anisotropy has been applied. The dislocation densities and the subgrain size-distributions in a MANET steel are investigated in the normal condition and after cyclic de ...
