    • 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 ...

    • Single-Lap-Joint Screening of Hysol EA 9309NA Epoxy Adhesive 

      Jensen, Robert E.; Flanagan, David P.; DeSchepper, Daniel C.; Silton, Miriam S.
      A commercial 2-part epoxy was evaluated per ARL-ADHES-QA-001.00 rev 1.0, which consists of single-lap-joint testing at room temperature and subsequent hot/wet and elevated temperature conditioning. This testing protocol ...
    • Spherical nanoindentation stress-strain curves of commercially pure titanium and Ti-6Al-4V 

      Weaver, Jordan S.; Priddy, Matthew W.; McDowell, David L.; Kalidindi, Surya R.
      Spherical nanoindentation combined with electron back-scattered diffraction was employed to characterize the grain-scale elastic and plastic anisotropy of single crystal alpha-Ti for commercially pure (CP-Ti) and alloyed ...
    • 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 ...
