Many properties in metallic glasses like diffusivity or ductility are affected by the concentration of the free volume. Hence, the determination of the concentration and the dependencies on experimental parameters are of major interest. For Zr46.8Ti8

The ripple topography of ion-beam–eroded surfaces offers a novel method to determine the shape of collision cascades and the distribution of deposited energy. From the energy dependence of the ripple spacing of Ar+- and Xe+-irradiated graphite surf

The surface topography of (0 0 0 1) highly oriented pyrolytic graphite eroded by Xenon ions at an incidence tilted relative to the surface normal was measured as function of the tilt angle θ and the ion energy E and fluence Φ by means of scanning t

Niobium films prepared by molecular beam epitaxy (MBE) and electron beam evaporation (EB) were loaded electrolytically with hydrogen. Out-of-plane strain and in-plane stresses during hydrogen loading were determined using X-ray diffraction and substr

The topography of (0001)-graphite (highly oriented pyrolytic graphite) surfaces eroded by a 5 keV ${\mathrm{Xe}}^{+}$ ion beam has been investigated using scanning tunneling microscopy. For tilted incidence of the ion beam and ion fluences of about $

We report on a small-angle x-ray-scattering (SAXS) and differential scanning calorimetry study of phase separation and crystallization in rapidly quenched amorphous Mg62Cu25Y10Li3 alloy samples. Differential scanning calorimetry demonstrates the occu
