Methane combustion over Pd/Ni-Al oxide catalysts: Effect of Ni/Al ratio in the Ni-Al oxide support

Korean Journal of Chemical Engineering, 2018
We prepared xNi-2Al oxide (x=0-1.1) supports via a hydrothermal method, and applied Pd/xNi-2Al catalysts in the catalytic methane combustion reaction. It was found that the physicochemical properties of the xNi-2Al supports varied as a function of the Ni content, and the interaction between support and impregnated Pd was also influenced by the Ni ...

Miscibility gap in Fe-Ni-Al and Fe-Ni-Al-Co systems

Metallurgical Transactions A, 1984
The phase equilibria in Fe-Ni-Al and Fe-Ni-Al-Co systems have been investigated by the diffusion couple technique, and the miscibility gap that separates α1 (Fe-rich disordered bcc phase) from α2 (NiAl-rich ordered bcc phase) has been determined. It has been ascertained that the three-dimensional shape of the miscibility gap is not simple helmetlike ...

Ordering reactions in Ni-Al-Mo-Ta and Ni-Al-Mo-W superalloys

Metallurgical Transactions A, 1985
The ordered structures formed in two experimental nickel base superalloys have been determined using selected area electron diffraction. Upon quenching from 1300 °C, the alloys contained ordered γ′ precipitates (L12 structure) and the matrix exhibited diffuse intensity at {1 1/2 0} positions, indicating the presence of short range order.

Internal oxidation of NiAl and NiAlSi alloys at the dissociation pressure of NiO

Acta Metallurgica et Materialia, 1994
Abstract NiAl and NiAlSi alloys were internally oxidized at temperatures of 1073–1273 K by the Rhines Pack method. For the NiAl alloy, the oxidation process follows parabolic law and the oxidation front was flat with severe integranular oxidation occurring at 1073 K and extensive grain boundary sliding at 1273 K.

Morphological and crystallographic features of ?-?? Ni-Al and Ni-Al-Ti two-phase bicrystals

Journal of Materials Science, 1982
Severalγ-γ′ Ni-Al and Ni-Al-Ti two-phase bicrystals were made by the solid-state diffusion couple method. Each couple consisted of aγ′-phase single crystal and a pure-Ni polycrystal, and was annealed at 1473 K in an Ar gas atmosphere. Single crystal layers ofγ-phase with uniform thickness always grow into the parentγ′-phase single crystals.

Effects of nanoscale Ni, Al, and Ni–Al interlayers on nucleation and growth of diamond on Si

Journal of Vacuum Science & Technology B, Nanotechnology and Microelectronics: Materials, Processing, Measurement, and Phenomena, 2010
Diamond nucleation experiments on Si wafers, precoated with Ni, Al, and Ni–Al duplex intermediate layers, have been conducted in a microwave plasma enhanced chemical vapor deposition reactor. The diamond nucleation density is dependent on the thickness of the single Ni interlayer and also the ratio of Ni/Al.
