    Time-of-Flight Texture Analysis of Limestone Standard: Dubna Results (1995)

    Notes: The pulsed reactor at the Joint Institute of Nuclear Research in Dubna, Russia, has been used to measure six pole figures of an experimentally deformed limestone sample that served as a round robin for neutron texture analysis. The time-of-flight data compare favourably with published results, both in resolution and texture information, and establish the technique as a viable alternative to more conventional methods of texture analysis.

    ROBL – a CRG beamline for radiochemistry and materials research at the ESRF (1999)
    Chester : International Union of Crystallography (IUCr)
    Journal of synchrotron radiation 6 (1999), S. 1076-1085

    Notes: The paper describes the Rossendorf beamline (ROBL) built by the Forschungszentrum Rossendorf at the ESRF. ROBL comprises two different and independently operating experimental stations: a radiochemistry laboratory for X-ray absorption spectroscopy of non-sealed radioactive samples and a general purpose materials research station for X-ray diffraction and reflectometry mainly of thin films and interfaces modified by ion beam techniques.

    Notes: Abstract Iron and magnesium are insoluble elements with each other and there is no phase diagram. However, it is possible to produce artificial alloys by ion implantation, in this study by iron implantation into magnesium. Samples are investigated by conversion electron Moessbauer spectroscopy, Auger electron spectroscopy and x-ray diffraction. While at low doses gaussian shaped iron profiles and paramagnetic doublets as Mössbauer spectra are obtained, the iron concentration reaches at the highest dose 90 at.-% in maximum and the Mössbauer spectrum shows a dominant ferromagnetic fraction. The x-ray diffraction pattern let conclude that a dilated α-iron lattice is formed. Microhardness of all samples is clearly increased due to the implantation.

    Alloying by high dose ion implantation of iron into magnesium and aluminium (1998)

    Notes: Abstract Alloys of the systems Fe–Al (mixable over the whole concentration range) and Fe–Mg (insoluble with each other) were produced by implantation of Fe ions into Al and Mg, respectively. The implantation energy was 200 keV and the ion doses ranged from 1 × 1014 to 9 × 1017cm-2The obtained implantation profiles were determined by Auger electron spectroscopy depth profiling. Maximum iron concentrations reached were up to 60 at.% for implantation into Al and 94 at.% for implantation into Mg. Phase analysis of the implanted layers was performed by conversion electron Mössbauer spectroscopy and X‐ray diffraction. For implantation into Mg, two different kinds of Mössbauer spectra were obtained: at low doses paramagnetic doublets indicating at least two different iron sites and at high doses a dominant ferromagnetic six‐line‐pattern with a small paramagnetic fraction. The X‐ray diffraction pattern concluded that in the latter case a dilated αiron lattice is formed. For implantation into Al, the Mössbauer spectra were doublet structures very similar to those obtained at amorphous Fe–Al alloys produced by rapid quenching methods. They also indicated at least two different main iron environments. For the highest implanted sample a ferromagnetic six‐line‐pattern with magnetic field values close to those of Fe3Al appeared.
