Interdiffusion in Cobalt-Nickel Alloys

Mechanical Properties of Electroformed Nickel Cobalt Alloys

Mechanical properties of nickel-cobalt alloys (0-10% Co) electroformed with low internal stress in sulfamate-based solutions were investigated in as deposited and heat treated conditions. It was demonstrated that alloy properties can be modified by selecting deposition conditions and alloy composition. Recommendations on alloy selection are made based on application requirements. The higher str...

" Catalytic Reactions on Iron / Cobalt and Iron / Nickel Alloys

First principles calculation of the interdiffusion coefficient in binary alloys.

The atomic mechanisms of diffusion in alloys are complex due to the variations of migration energies with environment and the correlations induced by short-range order between the different components. We present a first-principles approach for calculating vacancy-mediated diffusion coefficients in crystalline binary alloys and apply it to obtain the interdiffusion coefficient of Al(1-x)Lix. Th...

Nickel and cobalt release from metal alloys of tools--a current analysis in Germany.

BACKGROUND The former 'EU Nickel Directive' and, since 2009, the REACH Regulation (item 27 of Annex XVII) do not include all metallic objects. The nickel content of tools is not regulated by the REACH Regulation, even if they may come into in prolonged contact with the skin. Tools might be possible sources of nickel and cobalt sensitization, and may contribute to elicitation and maintenance of ...

The Structure of Intermediate Phases in Alloys of Titanium with Iron, Cobalt, and Nickel

The crystal structure of the intermediate phases in the binary systems of titanium with iron, cobalt, and nickel has been studied and the results compared with those previously published. The phases of the Ti2X type are face-centered cubic with % atoms per cell, and the TiX phases are body-centered cubic. TiFe, and Tic02 are hexagonal but not isomorphous. The nickel-rich phase has the compositi...
