EFFECT OF BALL-MILLING TREATMENT ON MICROSTRUCTURE OF IN SITU POWDER-IN-TUBE (PIT) MGB2 TAPE
(American Institute of Physics (AIP), 2012-06-25)
In an in situ powder-in-tube (PIT) fabrication of MgB2 superconducting tapes, it has been found that ball-milling treatment on a starting powder is effective for improving critical current density (Jc) of the MgB2 tapes. ...
TEM AND SEM ANALYSIS FOR FORMATION MECHANISM OF TIN WHISKERS
(Trans Tech Publications, 2012-07-09)
Close observation with a transmission electron microscope (TEM) and a scanning electron
microscope (SEM) was performed for the growth process of tin (Sn) whiskers on lead (Pb)-free
Sn-plating. Whiskers were formed on a ...
