AbstractAbstract
[en] An apparatus used for in-situ ion mixing and Rutherford Backscattering (RBS) analysis is described, and data re presented for thin film structures of the Ag-Si and Au-Si simple eutectic systems. Considerable preferred orientation in the Ag thin films was found which was not observed in the Au films although they were similarly prepared. This texturing is initially increased by Xe ion bombardment and then decreases (less preferred orientation), but even with approx. 1016 Xe cm-2 it is still far from random

AbstractAbstract
[en] Ion irradiation-induced mixing can be attributed to two principal types of processes; recoil implantation and cascade mixing, both of which may contribute significantly in bilayer mixing experiments. The influence of the chemical reactivity of the layers on these two mechanisms were examined in the mixing of Ti/SiO2, Cr/SiO2 and Ni/SiO2 bilayers induced by 290 keV Xe irradiation at irradiation temperatures of 77 to 750 K

AbstractAbstract
[en] There are two possible approaches to applying ion implantation to the modification of the corrosion behavior of metals and alloys. The first approach is to use ion implantation to produce metastable or amorphous corrosion-resistant surface alloys. Secondly, ion implantation can be used to introduce controlled amounts of various elements into the surface of a metal

AbstractAbstract
[en] Ion-induced mixing not only can lead to stable compound formation, but also to metastable alloy formation. The extension of terminal solubility from both sides of the phase-diagram eventually becomes structurally incompatible and a glassy (amorphous) mixture can form. The composition range where this bifurcation is likely to occur is in the two-phase regions of the phase diagram. These concepts are potentially useful guides in selecting metal pairs that form metallic glasses by ion mixing. In this report, phenomenological correlation between stable (and metastable) phase formation and phase diagram is discussed in terms of recent experimental data

AbstractAbstract
[en] The interpretation of ion mixing results involves the combination of thermodynamic and kinetic concepts. The use of thermodynamic concepts implies that local regions in the vicinity of a cascade achieve some form of metastable equilibrium during the relaxation period following prompt cascade events. This implies that within these local regions, certain thermodynamic variables have well defined averages (e.g. temperature, composition, etc.) while other variables (e.g. long range order) are constrained to assume non-equilibrium values by the kinetic restrictions imposed during the relaxation process following the prompt cascade events. In order to describe the metastable thermodynamics, one can use free energy diagrams. The diagrams describe both equilibrium and metastable equilibrium states

AbstractAbstract
[en] To investigate the role of the chemical nature of the medium and the impurity species in the ion mixing process, we have measured the apparent broadening of thin metal markers in SiO2 and compared it with the broadening of markers in Si. Samples consisted of markers of thicknesses of the order of approx. 10 A of W or Pt imbedded in Si, and of Pt, W, Hf, Co, Ni and Ti markers in SiO2

AbstractAbstract
[en] The phenomenon of ion mixing has many facets which are not yet well described in theory. Two general classes of models have been proposed: equilibrium models which describe transport resulting from thermal oscillation of the atoms in a high concentration of defects; and ballistic models in which the transport is the product of the radiation damage itself
