Defect structures in MgB2 wires introduced by hot isostatic pressing
X. Z. Liao, A. Serquis, Y. T. Zhu +6
The microstructures of MgB2 wires prepared by the powder-in-tube technique and subsequent hot isostatic pressing were investigated using transmission electron microscopy. Large amo…
Mg(B,O)2 precipitation in MgB2
X. Z. Liao, A. Serquis, Y. T. Zhu +5
MgB2 samples prepared by solid-state reaction were investigated using high-resolution transmission electron microscopy (HREM), X-ray energy-dispersive spectroscopy (EDX), electron…
Synthesis, characterization and ageing of MgB2
A. Serquis, R. Schulze, Y. T. Zhu +7
We studied the influence of sample preparation and defects in the superconducting properties samples using atomic ratios of Mg:B=1:1 and Mg:B=1:2. Samples were characterized by SEM…
Effect of lattice strain and defects on the superconductivity of MgB2
A. Serquis, Y. T. Zhu, E. J. Peterson +3
The influence of lattice strain and Mg vacancies on the superconducting properties of MgB2 samples has been investigated. High quality samples with sharp superconducting transition…
