Nature of Long-Range Order in Cu3+xAu1-x
(2003-11-17)The diffuse scattering and intensities of Bragg peaks from single crystals of Cu77Au23 and Cu78Au22 have been studied for various degrees of long‐range order. The results indicate that the excess Cu atoms, replacing Au in ... -
Ni Self-Diffusion
(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
(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 ... -
Phase equilibria and thermodynamic calculation of the CoeTa binary system
(2014-09-29)Experimental investigation and thermodynamic evaluation of the CoeTa binary phase diagram was carried out. Equilibrium compositions obtained in two-phase alloys and diffusion couples were measured by electron probe ... -
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 ... -
The Relation Between Bulk Modulus and Relative Enthalpy: a Broad-Based Thermodynamic Analysis and a Case Study on Aluminum
(2001-07-17)By postulating a linear relationship between logarithmic bulk modulus and relative enthalpy, we have developed in this paper a thermodynamic framework that provides a link between thermal properties and bulk modulus under ... -

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 ... -
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 ... -
