Raw and Processed Data to Generate Three-Dimensional Grain Map of Open-Cell Aluminum Foam
(2018-08-03)A three-dimensional grain map of an investment-cast, open-cell, aluminum foam is generated using a combination of experimentally derived and synthetically derived data. Specifically, the experimental data are derived from ... -
RbBr–TbBr3 Thermodynamic investigation
(2013-03-29)The thermodynamic properties and phase diagram of the RbBr–TbBr3 system were analyzed by means of the CALPHAD method in this work. Thermodynamic models were defined in order to describe the Gibbs energies of the individual ... -
Recrystallization of an AlMgSi alloy after different modes of hot deformation
(2013-12-03)Recrystallization of an AlMgSi alloy has been studied after deformation in torsion and plane strain compression. The main emphasis has been focused on describing the development of nuclei in shear deformed material, and a ... -
Rotary Forging
(2013-12-03)ROTARY FORGING, or orbital forging, is a two-die forging process that deforms only a small portion of the workpiece at a time in a continuous manner. Unfortunately, the term rotary forging is sometimes used to describe the ... -
SciPy
SciPy is a Python-based ecosystem of open-source software for mathematics, science, and engineering. Core packages include NumPy for arrays, the SciPy core scientific libraries, the MatPlotLib 2D visualization tool, the ... -
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 ...
