Alloy thermodynamics in nanostructures

Journal of Materials Research, 1994
The importance of the interactions between alloy atoms and topological defects for the thermodynamic properties of nanostructured alloys is pointed out. The McLean model for grain boundary segregation is extended to yield an expression for the total Gibbs free energy of an alloy polycrystal.

Microstructure of nanostructured Fe40Ni38Mo4B18 alloy

Journal of Materials Science, 1999
Nanostructured Fe40Ni38Mo4B18 specimens with a wide range of different nanostructures can be produced by annealing the amorphous alloy in the temperature range from 700 K to 1060 K. The nanostructured Fe40Ni38Mo4B18 specimens prepared between 700 K and 760 K have a microstructure of the 4–9 nm fcc (Fe, Ni) solid solution crystallites embedded in the ...

Fabrication of Alloyed Plasmonic Nanostructures

2018 International Conference on Optical MEMS and Nanophotonics (OMN), 2018
We have fabricated homogeneous thin films of an alloy of Au and Ag, by annealing two consecutive deposited layers of Au and Ag. We have also successfully fabricated nanodisks and nanorods made of AuAg alloys by annealing the nanostructures at 300 °C for 5 hours showing that the nanostructures retain their shape after annealing.

Nanostructured amorphous Si-Au alloys

Nanostructured Materials, 1994
Abstract Nanostructured amorphous Si 1-X Au X -alloys (0.1 ≤ x Au ≤ 0.3) were produced by an inert-gas condensation and in-situ consolidation technique and investigated by Small Angle Neutron Scattering (SANS) and density measurements. The results are interpreted in terms of a microstructure which consists of nanometer-sized amorphous grains ...

Embedded Binary Eutectic Alloy Nanostructures

JOM, 2012
The properties of binary eutectic alloy nanostructures embedded within a matrix are discussed. It is demonstrated that GeAu and GeSn nanostructures embedded in SiO2 form in a bilobed structure as predicted by a simple theory. Upon heating, the nanostructures melt and assume a nominally compositionally homogeneous structure.

The Portevin-Le Châtelier effect of gradient nanostructured 5182 aluminum alloy by surface mechanical attrition treatment

Journal of Materials Science & Technology, 2018
Nanocrystalline surface layers and gradient nanostructure in 5182 aluminum alloy have been produced through surface mechanical attrition treatment (SMAT). The results indicate that the gradient nanostructure can not only improve the mechanical properties

Nanostructured Bearing Alloy Studies.

1994
Abstract : Work prior to this reporting period focused on achieving a more inert atmosphere for handling and consolidation of the nano-scaled steel powders. As a result, oxygen content in the nano steel powder compacts has been decreased significantly. However, even the decreased level (3% to 5%) is still too high. Further, high carbon levels (6% to 10%
