Probing the three-dimensional strain inhomogeneity and equilibrium elastic properties of single crystal Ni nanowires
We employ three dimensional x-ray coherent diffraction imaging to map the lattice strain distribution, and to probe the elastic properties of a single crystalline Ni (001) nanowire grown vertically on an amorphous SiO2 k Si substrate. The reconstructed density maps show that with increasing wire width, the equilibrium compressive stress in the core region decreases sharply while the surface ten...

متن کاملinvestigation on elastic properties of ferromagnetic ni single crystal in magnetic field
elstic properties of nickel single crystal has been studied in magnetie fields ranging from 0 to 12 kgauss. comparison of the observed data shows that there might be an effect of changes in the rate of elongation due to the strangth of magnetic field in proportional region.
متن کاملEvaluating the Effect of Ta/W Ratio on Microstructure and Stress Rupture Properties of Ni-Based Single Crystal Superalloy PWA1483
In this study, the effect of Ta/W ratio on the microstructure and stress rupture properties of Ni-based single crystal (SX) superalloy PWA1483 was investigated. For this purpose, single crystal (SX) superalloys with different Ta/W ratios (0.75, 1.0, 1.32 and 1.5 in wt.%) were fabricated. The alloys were directionally solidified by Bridgman method under the same solidification condition at withd...
متن کاملThree-dimensional optical trapping and manipulation of single silver nanowires.
We report the first experimental realization of all-optical trapping and manipulation of plasmonic nanowires in three dimensions. The optical beam used for trapping is the Fourier transform of a linearly polarized Bessel beam (termed FT-Bessel). The extended depth of focus of this beam enables the use of a retroreflection geometry to cancel radiation pressure in the beam propagation direction, ...
