    • 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)
    • 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 ...
    • Synchrotron Diffraction and Composition Data Sets of Co-Fe-Zr Metallic Glasses 

      Fang, Ren; Mehta, Apurva; Williams, Travis; Hattrick-Simpers, Jason R (2017-07-12)
      The dataset summarizes a series of high-throughput studies on the Co-Fe-Zr metallic glass system with a total of 1323 unique alloys having been investigated. The primary goal of the work was to identify unsupervised ...
    • Temperature Dependece of the Elastic Constants of Aluminum 

      Tallon, J.L.; Wolfenden, A. (1979-03-02)
      The single crystal elastic constants of aluminum have been measured using a piezoelectric composite oscillator from room temperature to just 20K below the melting point. The elastic moduli differ markedly from previous ...
    • Temperature Variation of the Elastic Constants of Cubic Elements. I. Copper 

      Overton, W.C.; Gaffney, John (1954-09-08)
      The ultrasonic pulse technique has been used in conjunction with a specially devised cryogenic technique to measure the velocities of 10-Mc/sec acoustic waves in copper single crystals in the range from 4.2°K to 300°K. The ...
    • Thermal Dilation of Copper 

      Eppelsheimer, D.S.; Penman, R. R. (1950-01-07)
      The prediction that certain cubic metals may not be precisely cubic throughout a range of temperature below their melting points led to the present investigation. Pure copper was chosen as the cubic metal to examine for ...
    • The Thermal Expansion of Pure Metals: Copper, Gold, Aluminum, Nickel, and Iron 

      Nix, F. C.; MacNair, D. (1941-08-08)
      Extremely accurate determinations of the linear thermal expansions have been made interferometrically from — 196°C to temperatures about +400°C for Al and +700°C for Fe, Ni, Cu and Au. The relationship between true thermal ...
    • Tracer Diffusion of Magnesium in Aluminum Single Crystals 

      Rothman, S. J.; Peterson, N. L.; Nowick, L. J.; Robinson, L. C. (2014-02-16)
    • Ultrahigh Carbon Steel Microconstituent Annotations 

      DeCost, Brian; Hecht, Matthew; Sibley, Txai; Francis, Toby; Webler, Bryan; Picard, Yoosuf; Holm, Elizabeth (2018-05-04)
      This dataset consists of scanning electron micrographs accompanied by microconstituent annotations, and is intended as a community benchmark dataset for microstructure segmentation and clustering tasks. The dataset consists ...
