Dislocations in continuous filament reinforced W/NiAl and Al2O3/NiAl composites
Metallurgical and Materials Transactions A, 1997Continuous filament reinforced W/NiAl and Al2O3/NiAl composites (as-processed, annealed, and thermally cycled) have much higher dislocation densities than that of monolithic NiAl. These higher dislocation densities resulted from the relaxation of thermal residual stress, which developed during the cooling of the sample from elevated temperatures and ...

To ensure effective charge transfer dynamics at the interface of a double semiconductor system, a set of p–n heterojunction (p-CuFe2O4/n-NiAl-LDH) photocatalysts with varying LDH content was successfully designed through the co-precipitation method.

Vibratory cavitation erosion tests were carried out on as-cast NiAl intermetallic compounds containing 46.5 to 62.1 at pct Ni. The erosion rate decreased with increasing nickel content by over two orders of magnitude, from a high of 16.4 to 0.11 mg·h−1. These low erosion rates exhibited by the nickel-rich alloys containing 58 and 62.1 at.

Abstract The study applies nested arrays to previous works on the structure of systems on state-space form. The state-space form maps into a digraph, represented by a boolean matrix. Computational methods for potential controllability, cyclic components, loops, decomposition and piecewise eigenvalue calculation serve as examples.

Abstract A Ni 8.9 at.% Al single crystal was aged at 775 K for one day to establish a state of thermal equilibrium and subsequently quenched to room temperature where it was investigated by diffuse neutron scattering. In the elastic coherent scattering, short-range order scattering was separated from linear displacement scattering.

The intermetallic compound NiAl has been widely studied for its possible use as a high-temperature structural material.[1] The preparation of NiAl alloys of controlled composition and stoichiometry has been recognized to be an important component in their continued development and understanding.

Thickness scaling of NiAl thin films for alternative interconnect metallization
International Interconnect Technology Conference, 2020NiAl thin films have been studied as potential alternatives for the metallization of interconnects due to their relatively low bulk resistivity and high melting point.

In the earlier studies the phase {beta}-NiAl was found to be very oxidation resistant, forming a protective alumina scale in a wide range of temperature and oxygen pressure. However, in more recent studies many critical features were detected in this alumina formation and even accelerated attack by intergranular and internal oxidation was observed ...
