The tensile properties of irradiated Ni single crystals and their temperature dependence

Philippe Spätig, Robin Schäublin, Zhongwen Yao

Single-crystal nickel was irradiated with 590 MeV protons to 10(-1) dpa at room temperature. Irradiated and unirradiated tensile samples were deformed and relaxation tests were performed at temperatures between 77 and 423 K. The tests show a strong tempera ...

Mechanical behaviour of nanocrystalline electrodeposited Ni above room temperature

Philippe Spätig, Robin Schäublin, Florian Dalla Torre, Helena Van Swygenhoven

Tensile properties and microstructure of Danocrystalline electrodeposited Ni at temperatures between room temperature and 330&DEG; C are presented. Above 300&DEG; C low flow stress and high tensile elongation are observed along with grain growth and segreg ...

Dislocation defect interaction in irradiated Cu

Philippe Spätig, Robin Schäublin, Zhongwen Yao

Pure Cu single crystals irradiated at room temperature to low doses with 590MeV protons have been deformed in situ in a transmission electron microscope in order to identify the basic mechanisms at the origin of hardening. Cu irradiated to 10(-4) dpa shows ...

On the strain-hardening of tempered martensitic alloys

Philippe Spätig, Raul Alejandro Bonadé

The strain-hardening behaviour of a tempered martensitic iron-chromium-carbon model was examined in terms of dislocation mechanics. Tensile tests of this body-centered cubic alloy were carried out from 77 up to 293 K. A specific relationship between the fl ...

Assessment of irradiation-hardening on Eurofer97' and Zircaloy 2 with punch tests and finite-element modeling

Philippe Spätig, Emiliano Campitelli

We present an assessment of the mechanical constitutive behavior after irradiation for a tempered martensitic steel, Eurofer97', and for Zircaloy by means of small-ball punch tests. For that purpose we use a finite-element model of the punch test device. W ...
