Ni-Al 2 O 3 and Ni-Al composite high-aspect-ratio microstructures

SPIE Proceedings, 1998
High-aspect-ratio microstructures (HARMs) have a variety of potential applications in heat transfer, fluid mechanics, catalysts and other microelectromechanical systems (MEMS). The aim of this work is to demonstrate the feasibility to fabricate high performance particulate metal-matrix composite and intermetallic micromechanical structures using the ...

An unknown Ni-Al hydrosilicate

Acta Geologica Hungarica, 2003
An "unknown Ni-Al hydrosilicate" was found in the karstic nickel deposits in the localities Ba and Takovo in Serbia, and Aghios Ioannis in Greece. It occurs in fine-grained bluish-green and green aggregates with takovite and hydrated halloysite. It is an epigenetic product in the karstic nickel deposit.

2010
The effect of homogeneously distributed nanosized (1???8 nm) particles of ?????- and Ferich phases on the evolution of vacancy defects in electron irradiated Fe-Ni-Al alloy was investigated by positron annihilation spectroscopy. It was shown that presence of precipitates in an alloy leads to decrease in accumulation of vacancies several times in ...
