    • Ni Self-Diffusion 

      Maier, K; Mehrer, H; Lessmann, E; Schüle, W (2013-06-26)
      Self-diffusion in nickel single crystals is measured between 813 and 1193 K using ion-beam sputtering as a microsectioning technique. Gaussian activity-depth profiles are observed over about three orders of magnitude in ...
    • On the Anomalous Self-Diffusion in B.C.C. Titanium 

      Kohler, U; Herzig, C.H (2013-07-03)
      Self-diffusion of the Ti44 is measured in Beta-Titanium under UHV conditions int eh whole range of existence of the bcc phase. The Arrhenius plot shows a strong upward curvature in agreement with previous investigations ...
    • Self-Diffusion and fast cobalt impurity diffusion in the bulk and in grain boundaries of hexagonal titanium 

      Herzig, Christian; Willecke, Ralf; Vieregge, Klaus (2013-07-03)
      Bulk Self-Diffusion was measure in alpha-Titanium single crystals between 776 and 1132 K using the radiotracer Ti44 and ion beam sputtering for profile sectioning.
    • Self-diffusion in aluminum at low temperatures 

      Burke, J.; Ramachandran, T. R. (2014-01-20)
      Values of the self-diffusivity of pure aluminum in the temperature range 130∮ to 200° have been determined by measuring the rate of annealing of prismatic and faulted dislocation loops in thin foils of quenched 99.999 pct ...
    • Self-Diffusion in Solid Chromium 

      Hagel, W. C. (2013-07-08)
    • Study of Si self-diffusion by nuclear techniques 

      Demond, F. J.; Kalbitzer, S.; Mannsperger, H.; Damjantschitsch, H. (2014-02-10)
      By using ion implantation for preparation and p, γ-reactions for analysis of 30Si profiles the Si self-diffusion has been studied in the temperature range of 830–1200°C. The results reveal unambiguously that the diffusion ...
    • Tracer Diffusion of Magnesium in Aluminum Single Crystals 

      Rothman, S. J.; Peterson, N. L.; Nowick, L. J.; Robinson, L. C. (2014-02-16)
