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 ...

Plastic flow of martensitic model alloys

Philippe Spätig, Robin Schäublin, Raul Alejandro Bonadé

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 ...

The microstructure and associated tensile properties of irradiated fcc and bcc metals

Nadine Baluc, Yong Dai

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 ...

2000

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 ...

Tensile properties and microstructure of 590 MeV proton-irradiated pure Fe and a Fe-Cr alloy

Polycrystalline pure Fe and Fe-12Cr alloy have been proton-irradiated to doses of 10(-3)-3 x 10(-1) dpa at room temperature and 523 K. Samples were mechanically tested in tension and transmission electron microscopy (TEM) was performed on the as-irradiated ...

A "breathing" model for the polarization response of relaxer ferroelectrics

Alexander Tagantsev

The present paper proposes a model of relaxer ferroelectrics, which describes the polarization response of these materials in terms of vibration of the interphase boundary between the polar regions and nonpolar matrix. The model is formulated and is applie ...

Tensile specimens of pure Mo and Mo-5 Re, Mo-41 Re and TZM alloys have been irradiated with 600 MeV protons in the PIREX facility at 300 and 660 K to 0.5 dpa. Results of the postirradiation tensile testing show a strong radiation hardening and a severe los ...
