摘要：
Critical current density J(c) in Ag-sheathed Bi-2223 superconducting tapes was improved by applying the vibrational aligning technique, Microstructure analyses, X-ray diffraction and Vickers hardness were performed. The vibrational specimens showed a higher density and better grain alignment compared to conventional specimens. (C) 1998 Elsevier Science B.V.
