Shape memory and superelasticity in polycrystalline Cu–Al–Ni microwires

We report a strategy to significantly improve the ductility and achieve large superelastic and shape memory strains in polycrystalline Cu–Al–Ni shape memory alloys that are normally brittle. We use a liquid-phase Taylor wire forming process to obtain microwires of 10–150 m diameter with a bamboo grain structure. The reduction of grain boundary area, removal of triple junctions, and introduction...

The extraordinary Hall effect in coherent epitaxial 7 (Mn,Ni)Al thin films on GaAs

Ultrathin coherent epitaxial films of ferromagnetic T(Mn,Ni)O,,oA1,S, have been grown by molecular beam epitaxy on GaAs substrates. X-ray scattering and cross-sectional transmission electron microscopy measurements confirm that the c axis of the tetragonal 7 unit cell is aligned normal to the (001) GaAs substrate. Measurements of the extraordinary Hall effect (EHE) show that the films are perpe...

Shape Memory Properties in Cu-Zn-Al Alloy

In this research a Cu-Zn-Al alloy is produced by melting the raw materials in an electric resistance furnace and then pouring it into a steel mould. The optimum way to achieve the final analysis in the hypo-eutectoid range is determined and the influence of the alloying element, Ti on the grain size and the shape memory properties of the samples are investigated. Solution treatment (done at 850...

Thin Al, Au, Cu, Ni, Fe, and Ta films as oxidation barriers for Co in air

We have investigated the effectiveness of Al, Au, Cu, Ni, Fe, and Ta films with thicknesses up to 4 nm for protecting a Co surface from oxidation in air at room temperature. The distinct change in the Co 2p3/2 core-level line shape observed by x-ray photoelectron spectroscopy upon the oxidation of Co makes it a simple matter to identify the fractions of the Co that are in the metallic state and...
