Anomalous phonon behavior in the high-temperature shape-memory alloy Ti50Pd50â‹TMxCrx

Ti50Pd50−xCrx is a high-temperature shape-memory alloy with a martensitic transformation temperature strongly dependent on the Cr composition. Prior to the transformation, a premartensitic phase is present with an incommensurate modulated cubic lattice with wave vector of q0=(0.22,0.22,0). The temperature dependence of the diffuse scattering in the cubic phase is measured as a function temperat...

Serration Behavior in Pd77.5Cu6Si16.5 Alloy

The strain-rate-dependent plasticity under uniaxial compression at the strain rates of 2× 10−3, 2 × 10−4 and 2 × 10−5 s−1 in a Pd77.5Cu6Si16.5 alloy is investigated. At different strain rates, the serration events exhibit different amplitudes and time scales. The intersection effects take place obviously, and the loading time is much longer than the relaxation time in the serration event at thr...

Perpendicular Magnetic Anisotropy in Heusler Alloy Films and Their Magnetoresistive Junctions

For the sustainable development of spintronic devices, a half-metallic ferromagnetic film needs to be developed as a spin source with exhibiting 100% spin polarisation at its Fermi level at room temperature. One of the most promising candidates for such a film is a Heusler-alloy film, which has already been proven to achieve the half-metallicity in the bulk region of the film. The Heusler alloy...

Anomalous yielding in the complex metallic alloy Al13Co4

The single crystal deformation behaviour of orthorhombic Al13Co4 has been studied below the brittle-ductile transition temperature observed in bulk material from room temperature to 600 C, using indentation, microcompression and transmission electron microscopy. At room temperature, slip occurred most easily by dislocation motion on the (001)[010] slip system, as observed in the ductile regime ...
