Microstructural development under irradiation in European ODS ferritic/martensitic steels

Nadine Baluc, Robin Schäublin, Amuthan Ramar

Oxide dispersion strengthened steels based on the ferritic/martensitic steel EUROFER97 are promising candidates for a fusion reactor because of their improved high temperature mechanical properties and their potential higher radiation resistance relative t ...

Nanostructured tungsten-iron alloy prepared by electrodeposition

Nadine Baluc, Robin Schäublin

Tungsten-iron alloy was produced by electrodeposition. The electrodeposited alloy (15 at.% W) possesses a two-phase composite microstructure, containing a nanocrystalline phase of distorted BCC structure with a grain size between 50 to 150 nm and an amorph ...

Fabrication of curved-line nanostructures on membranes for transmission electron microscopy investigations of domain walls

Robin Schäublin, Christian David

We have fabricated curved-line ferromagnetic nanostructures on membranes for transmission electron microscopy investigations of the equilibrium magnetic spin configurations. The magnetic elements were fabricated using electron-beam lithography and a lift-o ...

Effect of helium on irradiation-induced hardening of iron: A simulation point of view

Robin Schäublin

Irradiation-induced hardening and loss of ductility of ferritic/martensitic materials envisaged for future fusion reactor is still difficult to understand. In particular, helium (He), produced by transmutation by the fusion neutrons of 14 MeV, is known to ...

Nanometric crystal defects in transmission electron microscopy

Robin Schäublin

Transmission electron microscopy (TEM) is revisited in order to define methods for the identification of nanometric defects. Nanometric crystal defects play an important role as they influence, generally in a detrimental way, physical properties. For insta ...

The effect of point defects on the martensitic phase transformation

Robin Schäublin, Jian Wang, Yi Wang

Martensitic Ni-Ti was observed to transform to the austenitic phase due to defects introduced either by ion or electron irradiations at a temperature where the martensitic phase is normally stable. The phenomenon was studied by molecular dynamics simulatio ...

Deformation behaviour and microstructure of nanocrystalline electrodeposited and high pressure torsioned nickel

Philippe Spätig, Robin Schäublin, Florian Dalla Torre

Microstructural analysis and mechanical testing have been performed on two types of nanocrystalline (NC) Ni samples and compared to coarse-grained (CG) Ni. The NC electrodeposited (ED) Ni is characterized by a mean grain size of 21 nm, a narrow grain size ...

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 ...

Molecular dynamics simulations of phase formation and stability in the Al(Ni) system under irradiation

Robin Schäublin

Molecular dynamics simulations of displacement cascades in aluminium, aluminium-nickel solid solutions and inhomogeneous samples containing amorphous or crystalline Al3Ni precipitates are performed. It is shown that no segregation occurs inside the displac ...

Temperature dependence of irradiation effects in pure titanium

Nadine Baluc, Robin Schäublin

The microstructural modifications due to irradiation in hcp pure metals and their consequences on the mechanical properties have been investigated. Experimental results for proton-irradiated pure polycrystalline titanium are presented and discussed. Sample ...

Irradiation-induced phase transformation in undeformed and deformed NiTi shape memory thin films by high-energy ion beams

Robin Schäublin, Thomas La Grange

Irradiation-induced transformations in sputter-deposited Ti-rich NiTi thin films have been investigated with special attention given to the effects of prior deformation on the response of martensite phase. Irradiation at low fluence was carried out at room ...

Present development status of EUROFER and ODS-EUROFER for application in blanket concepts

Nadine Baluc, Robin Schäublin, Cyril Cayron

Within the European Union, the two major breeding blanket concepts presently being developed are the helium cooled pebble bed (HCPB), and the helium cooled lithium lead (HCLL) blankets. For both concepts, different conceptual designs are being discussed wi ...

Irradiation-induced stacking fault tetrahedra in fcc metals

Nadine Baluc, Robin Schäublin, Zhongwen Yao

Irradiation induces the formation of stacking fault tetrahedra (SFTs) in a number of fcc metals, such as stainless steel and pure copper. In order to understand the role of the material's parameters on this formation, pure Cu, Ni, Pd and Al, having a respe ...
