Significant hardening effect due to Fe concentrations in Ni-based alloys with face-centered-cubic structure has been studied by using a combined experimental and atomistic-based computational approach via nanoindentation tests. The obtained load–displacement data for the [0 0 1] crystal orientation reached qualitative good agreement molecular dynamics simulations results, leading strong evidence that main strengthening factors are associated sluggish dislocation diffusion, reduced defect...
The pyrochlore oxides (A2B2O7) exhibit a remarkable range of structural, physical, and magnetic properties related to their various chemical compositions. This article reports the phase transformations induced by high electronic excitation in pyrochlores Gd2(ZrxTi1−x)2O7 family irradiated with swift ions. structural changes, investigated using several analytical techniques (x-ray diffraction, Raman spectroscopy, transmission electron microscopy), strongly depend on composition. along ion...
6H-SiC and 3C-SiC single crystals were simultaneously irradiated at room temperature with 100 keV Fe ions fluences up to 4 × 10 14 cm −2 (∼0.7 dpa), i.e. amorphization. The disordering behaviour of both polytypes has been investigated by means Rutherford backscattering spectrometry in the channelling mode synchrotron x-ray diffraction. For first time, it is experimentally demonstrated that general damage build-up similar polytypes. At low dose, irradiation induces formation small...
The next step in the Wendelstein stellarator line is large superconducting device 7-X, currently under construction Greifswald, Germany. Steady-state operation an intrinsic feature of stellarators, and one key element 7-X mission to demonstrate steady-state plasma conditions relevant for a fusion power plant. device, on hand, requires implementation special technologies, giving rise technical challenges during design, fabrication assembly such device. On other also physics development at...
This work reports the study, via combination of Rutherford backscattering spectrometry and channeling, x-ray diffraction, transmission electron microscopy experiments, damage formation in cubic yttria-stabilized zirconia single crystals irradiated with medium-energy (4 MeV) heavy (Au) ions. The buildup, which is accounted for framework multistep accumulation model, occurs three steps. first step at low fluences (up to 1015 cm−2), characterized by a regular increase both yield elastic strain,...
Structural, mechanical, and dimensional evolutions of silicon carbide (SiC) induced by heavy-ion irradiations are studied means Rutherford backscattering spectrometry channeling (RBS/C), nanoindentation, surface profilometry measurements. 4H- 6H-SiC single crystals were irradiated with 4 MeV Au2+ Xe+ ions at room temperature (RT) or 400 °C. Using a Monte Carlo program to simulate the RBS/C spectra (MCCHASY code), we find that Au ion irradiation RT induces total sublattice disorder related...
The early stages of nucleation and growth dislocations by irradiation in urania is clarified based on the combination experiments atomistic calculations. It established that induced follow a five stage process: (i) point defects are first created irradiation, (ii) they aggregate into clusters, (iii) from which nucleate Frank loops, (iv) transform unfaulted loops via Shockley turn grow, (v) finally reorganize forest dislocations. Stages (i)–(iii) participate lattice expansion while onset...
Microstructure and nanohardness of a nearly equimolar W-Ta-Cr-V high entropy alloy (HEA), as well its irradiation response under He+ irradiation, were investigated. The single-phase body-centered cubic nanostructured with 1 µm thick layer was fabricated on silicon substrate using magnetron sputtering method. HEA film has complex microstructure consisting micrometric domains that exhibit internal nanostructure controlled by their crystal orientation. measured the is 13±2 GPa, which...

This article presents a study of the damage production in yttria-stabilized cubic zirconia single crystals irradiated with swift heavy ions. The combination techniques which probe material at different spatial scales (Rutherford backscattering spectrometry channeling geometry, x-ray diffraction, transmission electron microscopy, and atomic force microscopy) was used order to gain information about depth distribution, disordering buildup, nature radiation defects, occurrence microstructural...
The structural transformations induced in Gd${}_{2}$Ti${}_{2}$O${}_{7}$ single crystals irradiated at high energies (870-MeV Xe), where ionization processes (electronic stopping) dominate, and low (4-MeV Au), ballistic (nuclear have been studied via the combination of Rutherford backscattering spectrometry channeling (RBS/C), Raman spectroscopy, transmission electron microscopy (TEM) experiments. At energy, amorphization occurs directly individual ion tracks from extreme electronic-energy...
