Magnetic measurement of nanocrystalline alloy based on a single sheet tester

Comparative Harmonic Loss Measurement of Grain Oriented and Non-oriented Magnetic Sheets Using a High Precision Single Sheet Tester

 Abstract: Local flux may be distorted in many regions of core, although total flux is usually sinusoidal. When attempting to predict the loss distribution in materials operating under localized distorted flux conditions, which occur in machines and transformer cores, it is essential that proper account of the waveform be taken. Moreover for development of new magnetic materials and generation ...

The Effects of Forming Parameters on the Single Point Incremental Forming of 1050 Aluminum Alloy Sheet

The single point incremental forming (SPIF) is one of the dieless forming processes which is widely used in the sheet metal forming. The correct selection of the SPIF parameters influences the formability and quality of the product. In the present study, the Gurson-Tvergaard Needleman (GTN) damage model was used for the fracture prediction in the numerical simulation of the SPIF process of alum...

Magnetic domain observations in a FeCo-based nanocrystalline alloy by Lorentz microscopy

Lorentz microscopy was used to investigate the domain structure in an Fe0.5Co0.5 80Nb4B13Ge2Cu1 alloy annealed at 500, 550, and 610 °C, respectively, for 1 h. The average grain size d, observed by conventional transmission electron microscopy, is 10 nm for the alloy annealed at 500 °C, 18 nm for 550 °C, and 90 nm for 610 °C. The domain structure of sample annealed at 500 °C exhibits few pinning...

Single Electron Devices Based on Nanocrystalline Silicon

nano-crystalline Si dots of dimensions of 8nm have been incorporated into a variety of Coulomb blockade and floating gate memory devices. Structures include vertical transistor, planar electrode, nanoscale channel junction and 2-gate trench structure. Ballistic transport, Coulomb oscillation and memory effects are clearly demonstrated
