Аннотация:
The effects of hot pressing (HP) on the critical current density of Ag-clad Bi(2223) superconducting tapes were investigated in detail. Results show that temperature, percentage reduction and reduction rate have a crucial influence on . At 77 K and 0 T, the best value of has been measured on the tapes with a percentage reduction of 20% after HP under a pressure of 200 MPa at C.
