We used density-functional theory to assess the electronic structure, elastic properties and planar fault energies of the B2 Ti(AlxNb1-x) (0.2 ≤ x ≤ 0.8) phase in relation to the composition and chemical ordering. We found that the covalent bonding becomes stronger for B2 Ti(AlxNb1-x) ...

Among the lowest temperature glasses are lead borates, generally of high lead oxide content with additions of B2O3, ZnO2, SiO2, and Al2O3. The eutectic of the PbOB2O3 system occurs at 490 °C (87.5% PbO/12.5% B2O3). Phosphorus doping and the addition of other materials, such as ...

1b and grips the wire lead at tip surface 16 which is generally in the order of 3 mils long on a side. Tip surface 16 grips the wire and wipes the wire against the contact to which the wire is to be bonded. If surface 16 has a relatively smooth surface having a microfinish less ...
. XRD results revealed that the HP films with DIM mixing and powder crystal grow without any remanence of the PbI2peak suggesting a strong tendency for the formation of a new crystal phase. Besides that, XRD patterns (Fig. S3a2-b2) demonstrated a more intensified XRD peak at 2θ<10ofor ...
In order to evaluate the compatibility of these alloys with the electroless nickel layer, solder bump shear tests were performed as a function of number of reflow cycles. Results show no degradation in shear load or failure mode among all three of the alloys tested, indicating no critical ...
We use comparative natural bond orbital (NBO) and quantum theory of atoms in molecules (QTAIM) methods to analyze the proximal bay-type H···H interactions in cis-2-butene and related species, which lead to controversial interpretation as attractive "HH bonding" in the QTAIM framework. We ...
The Young's modulus is in the order of HfB2ZB2NbB2TaB2YB2. As a results of these calculations, YB2 is predicted to have the best thermal shock resistance since it has the lowest Young's modulus. The brittleness, based on the calculated solidity index S=0.75G/B, is estimated in the...
such that the trailing wheel assembly simultaneously bonds, sets and cools the core/hot melt strand onto the bonding surface. In such instances, the present invention allows for very close proximity (on the order of a few centimeters) between the tip of the bonding shoe and the nip point of...
