Mechanical and microstructural characteristics of Ti6Al4V/AA2519 and Ti6Al4V/AA1050/AA2519 laminates manufactured by explosive welding

The aim of the work was to produce laminated structures consisting of Ti-6Al-4V alloy and AA2519 plates and to investigate their microstructure and mechanical properties with anemphasis on the role of an additional AA1050 interlayer. Explosive welding was ...

Electromagnon dispersion probed by inelastic X-ray scattering in LiCrO2

Henrik Moodysson Rønnow, Christian Rüegg, Sándor Tóth

Inelastic X-ray scattering with meV energy resolution (IXS) is an ideal tool to measure collective excitations in solids and liquids. In non-resonant scattering condition, the cross-section is strongly dominated by lattice vibrations (phonons). However, it ...

Direct observation of nanoscale interface phase in the superconducting chalcogenide KxFe2-ySe2 with intrinsic phase separation

Davide Innocenti

We have used scanning micro x-ray diffraction to characterize different phases in superconducting KxFe2-ySe2 as a function of temperature, unveiling the thermal evolution across the superconducting transition temperature (T-c similar to 32 K), phase separa ...

Tuning the metal-insulator transition in NdNiO3 heterostructures via Fermi surface instability and spin fluctuations

Joël Mesot, Elia Razzoli, Zoran Ristic

We employed in situ pulsed laser deposition (PLD) and angle-resolved photoemission spectroscopy (ARPES) to investigate the mechanism of the metal-insulator transition (MIT) in NdNiO3 (NNO) thin films, grown on NdGaO3(110) and LaAlO3(100) substrates. In the ...

High pressure phase transition in FeTe2O5Cl

Helmuth Berger

Raman and optical absorption spectra of FeTe2O5Cl at pressures (P) up to 5.9 GPa were measured in order to identify the point of pressure-induced structural phase transition and to compare the vibrational and optical properties of FeTe2O5Cl to those of FeT ...

Theory of percolation and tunneling regimes in nanogranular metal films

Claudio Grimaldi

Nanogranular metal composites, consisting of immiscible metallic and insulating phases deposited on a substrate, are characterized by two distinct electronic transport regimes depending on the relative amount of the metallic phase. At sufficiently large me ...

Flow microcapillary plasma mass spectrometry-based investigation of new Al–Cr–Fe complex metallic alloy passivation

Christian Ludwig, Noémie Elise Ott, Andrea Ulrich

Al-Cr-Fe complex metallic alloys are new intermetallic phases with low surface energy, low friction, and high corrosion resistance down to very low pH values (0-2). Flow microcapillary plasma mass spectrometry under potentiostatic control was used to chara ...

Massively parallel molecular dynamics simulation of formation of clathrate-hydrate precursors at planar water-methane interfaces: Insights into heterogeneous nucleation

Simone Meloni

The formation of methane-hydrate precursors at large planar water-methane interfaces has been studied using massively parallel molecular dynamics in systems of varying size from around 10 000 to almost 7 x 10(6) molecules. This process took two distinct st ...

Structural, physical and damping properties of melt-spun Ni-Mn-Ga wire-epoxy composites

Véronique Michaud, Susanne Glock

Ni-Mn-Ga is a ferromagnetic shape memory alloy that exhibits large, magnetic-field- and stress-induced strains via energy dissipating twinning when processed into single crystals. Grain boundaries suppress twinning and render polycrystalline Ni-Mn-Ga britt ...

Isothermal Ageing of SnAgCu Solder Alloys: Three-Dimensional Morphometry Analysis of Microstructural Evolution and Its Effects on Mechanical Response

John Botsis, Joël Cugnoni, Milad Maleki

Due to the high homologous temperature and fast cooling rates, the microstructures of SnAgCu (SAC) solders are in a meta-stable state in most applications, which is the cause of significant microstructural evolution and continuous variation in the mechanic ...
