Electrical and microstructural properties of superconducting MgB 2/Mg composites
(Trans Tech Publications, 2004)
MgB2/Mg composites were prepared to improve mechanical properties of brittle superconducting MgB2. MgB2 and Mg powders were mixed at different weight ratios and uniaxially pressed in a cylindrical dye at 0.5 GPa and at ...
Microstructural and electrical characterization of Ti and Mg doped Cu-clad MgB2 superconducting wires
(National Institute of Optoelectronics, 2005-02)
The recent studies on Ti doping effect on the critical current density (Jc) of MgB2 composite superconductors prepared under ambient pressure has shown an important enhancement at 20 K. In the present work, we have fabricated ...
Low-field behavior of Ti-added MgB2/Cu superconducting wires
We report on low-field magnetic properties of Ti-added (0-20 wt.% of Ti) Cu-clad MgB2 superconducting wires. Wires were produced by mixing appropriate amount of Ti and reacted MgB2 powder which was then placed inside Cu ...
