MICROSTRUCTURES OF MGB2 /FE TAPES FABRICATED BY AN IN SITU POWDER-IN-TUBE METHOD USING MGH2 AS A PRECURSOR POWDER
(IOP, 2006-01-04)
Microstructures of MgB2/Fe tapes fabricated by an in situ powder-in-tube method using MgH2 as a precursor powder have been studied by means of x-ray diffraction and analytical transmission electron microscopy combined with ...
RELATIONSHIP BETWEEN MICROSTRUCTURE AND JC PROPERTY IN MGB2/Α-AL2O3 FILM FABRICATED BY IN SITU ELECTRON BEAM EVAPORATION
(IOP, 2005-08-09)
A transmission electron microscopy (TEM) study has been carried out on an MgB2/α-Al2O3 film that exhibits the typical property of critical current density (Jc) under magnetic fields. The MgB2 layer of 300 nm in thickness ...
EFFECTS OF HEAT TREATMENTS ON MICROSTRUCTURE FORMATION IN MGB 2 /YSZ/HASTELLOY FILM
(2005-06)
Annealing processes in MgB2 films deposited on yttria-stabilized zirconia (YSZ)-buffered Hastelloy substrates were studied by transmission electron microscopy. The MgB2 films with Mg-rich compositions were fabricated at room ...
ELECTRON MICROSCOPY OF MGB2 THIN FILM ON YSZ-BUFFERED HASTELLOY
(Elsevier, 2004-06-11)
In order to understand the relationship between the microstructures and superconducting properties of MgB2 films, analytical TEM observations have been carried out. The films were fabricated by a KrF excimer laser deposition ...
MgB fiLMS WITH VERY HIGH CRITICAL CURRENT DENSITIES DUE TO STRONG GRAIN BOUNDARY PINNING
(American Institute of Physics, 2004-08-13)
MgB2 superconductor has a great potential for applications because of its high Tc and Bc2, exceeding those of any Nb-base superconductors at any temperature. It is now important to understand its flux pinning so as to raise ...
PROPERTIES OF MGB FILMS WITH VERY HIGH TRANSPORT CRITICAL CURRENT DENSITIES
(IEEE, 2005-06)
Magnesium diboride, MgB2, thin films are fabricated through two different kinds of process. One is an in-situ process by using electron beam deposition and the other is an ex-situ process by using the combination of pulsed ...
TRANSMISSION ELECTRON MICROSCOPY ANALYSIS OF C4H4S-doped MgB2 TAPES
(IOP, 2008)
It has been reported that doping with aromatic hydrocarbons in an in situ powder-intube
fabrication process of MgB2 tapes is effective for increasing the critical current density (Jc) under magnetic fields. In this study, ...
