We present a detailed analysis of the effect of the sheath materials on the microstructure and superconducting properties of MgB2 wires produced by the powder-in-tube method (PIT). We reduced commercial MgB2 powder by attrition milling in nitrogen at

In this work, we present the characterization of Ti sheathed MgB $_2$ wires prepared by PIT with two different cross-sections: circular and hexagonal. We determined the crystallographic texture of both the Ti sheath and the MgB $_2$ core by X-ray dif

The presence of texture in Ti sheathed MgB2 cables, induced by the manufacturing process, have been evaluated using XRD pole figures. Drawn monofilamentary and rolled multifilamentary cables have been compared in order to determine the effect of diff

MgB $$_{2}$$ has become a commercially attractive material for technological applications for its particular superconducting properties. However, due to its brittleness to obtain wires, a metallic sheath is needed for drawing. In the present work, gr

The effect of adding submicrometre ceramic particles during the fabrication of AlSi6Cu4 foams by indirect foaming is studied. Particles in the range of 0·4–0·7 μm are selected to analyse the feasibility of foam stabilisation with low quantities

The discovery of superconductivity at 39 K in MgB2 has been catching the attention of scientists due to the possibility of applying the material in magnets and electronic devices operating with cryocoolers (temperatures around 20 K). In the present w
