Selecting Aluminum Alloys to Resist Failure by Fracture Mechanisms
(2013-12-03)Though virtually all design and standard specifications require the definition of tensile properties for a material, these data are only partly indicative of mechanical resistance to failure in service. Except for those ... -
Self-Diffusion and fast cobalt impurity diffusion in the bulk and in grain boundaries of hexagonal titanium
(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
(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 ... -

Sensitivity of gold nano conductors to voids, substitutions and electric field: ab initio results
(2014-09-26)Gold nanowires are good candidates for nanoelectronics devices. A previous study has shown that the beryllium terminated BeO (0001) surface may be a useful platform for supporting nano gold conductors, since it preserves ... -
Si-Sr thermodynamic reassessment
(2013-04-01)The Si–Sr binary system has been thermodynamically reassessed in the present work based on the critically reviewed experimental data available in the literature, especially newly published experimental phase diagram data ... -
SiC-AlN, SiC-GaN and SiC-InN: wurtzite-structure quasibinary systems
(2013-04-08)The cluster-expansion method was used to perform first principles phase diagram calculations for the wurtzite-structure quasibinary systems (SiC)1-X(AlN)X, (SiC)1-X (GaN)X and (SiC)1-X(InN)X; and to model variations of ... -
SIESTA
One DFT code that can handle (at least) principally thousands of atoms. Basis functions are atomic orbitals. / SIESTA is both a method and its computer program implementation, to perform efficient electronic structure ... -
Single-Lap-Joint Screening of Hysol EA 9309NA Epoxy Adhesive
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 ... -
Solidification During Casting of Metal-Matrix Composites
(2013-12-03)Metal-matrix composites (MMCs) are engineered combinations of two or more materials in which reinforcing phases are dispersed in a metal or an alloy. Structurally, cast MMCs consist of continuous or discontinuous fibers ... -
Spherical nanoindentation stress-strain curves of commercially pure titanium and Ti-6Al-4V
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 ... -
Spherical nanoindentation stress-strain curves of primary-α grains in Ti5-2.5, Ti811, Ti64, Ti6242 and Ti6246 alloys
Recently established spherical indentation stress-strain protocols have demonstrated the feasibility of measuring reliably the mechanical responses at different material structure length scales in a broad range of structural ... -
