Plasticity of microcast aluminium wires

Andreas Mortensen, Jérôme Krebs, Suzanne Godelieve Alphonsine Verheyden

A microcasting process is developed for the production of monocrystalline microwires of pure and alloyed aluminium. The process is based on pressure infiltration of single-crystalline salt moulds; it is capable of producing wires with a diameter between 6 ...

Cast aluminium microwires

Jérôme Krebs

Plasticity size effects have been the focus of strong recent interest due to the miniaturization of devices such as actuators and different medical apparatuses. Devices with a sub-micrometre dimension have a high market potential and therefore a thorough u ...

Characterization of Mechanical Properties of MgB2 Conductor for the Superconducting Link Project at CERN

Barbora Bártová

In the framework of high luminosity upgrade of Large Hadron Collider at CERN, superconducting links are being developed. MgB2 wire is a candidate conductor for use in high- current cables. Mechanical properties of this material are of key importance for th ...

Evaluation of the interfacial shear strength between pseudoplastic NiTi shape memory alloy wires and epoxy by the pull-out method

Véronique Michaud, Yves Leterrier, Edgars Sparnins

The interfacial shear strength (IFSS) between nickel-titanium (NiTi) shape memory alloy wires, characterized by a nonlinear stress-strain behavior, and epoxy matrix was determined by pull-out tests. Tests were carried out at several temperatures and levels ...

Theoretical and Experimental Investigation of Flex-PCB Air-Gap Windings in Slotless BLDC Machines

Yves Perriard, Miroslav Markovic, Bruno Dehez, François Baudart

Slotless brushless dc motors find more and more applications due to their high performance and their low production cost. This paper focuses on the windings inserted in the air gap of these motors and, in particular, to an original production technique tha ...

Fabrication Trials of Round Strands Composed of Coated Conductor Tapes

Pierluigi Bruzzone, Davide Uglietti, Rainer Wesche

Various techniques have been proposed in order to assemble coated conductor tapes into high current strands. In this work, the preparation of high current capacity round strands starting from industrial coated conductors has been investigated. Round, twist ...

Status of Conductor Qualification for the ITER Central Solenoid

Pierluigi Bruzzone, Boris Stepanov

The ITER central solenoid (CS) must be capable of driving inductively 30 000 15 MA plasma pulses with a burn duration of 400 s. This implies that during the lifetime of the machine, the CS, comprised of six independently powered coil modules, will have to ...

MgB2 Hollow Wires and Cables Embedded in a Mg Alloy Matrix

Pierluigi Bruzzone, Davide Uglietti

The brittleness of the MgB2 wires prevents performing a cable architecture with very small bending radius, similar to NbTi Rutherford cables. Consequently, it is important to reduce the thickness of the superconducting materials in order to increase its be ...

Field- and geometry-controlled avoided crossings of spin-wave modes in reprogrammable magnonic crystals

Dirk Grundler

We study the spin dynamics in arrays of densely packed submicron Ni80Fe20 wires which form one-dimensional magnonic crystals. They are subject to an in-plane magnetic field H being collinear with the wires. In the case when neighboring wires are magnetized ...
