Publikováno v: MATERIALS TRANSACTIONS. 51(9):1663-1670

Critical current of bent-damaged Bi2223 composite tape differs from specimen to specimen. To describe the distributed critical current values of specimens, the three-parameter Weibull distribution function has been employed and has been demonstrated

Three-Directional FEM Analyses of Pre-Bending Effects for ${\rm Nb}_{3}{\rm Sn}$ Composite Wires

Autor: I. Okada, Hidetoshi Oguro, N. Nanato, M. Wake, SeokBeom Kim, Gen Nishijima, Satoru Murase, Satoshi Awaji, K. Watanabe, K. Kiyama

Publikováno v: IEEE Transactions on Applied Superconductivity. 17:2676-2679

Pre-bending effects of Nb3Sn composite wires, enhancement in Jc at the as-cooled condition and Jc peak, Jcm, against applied tensile strain, are well known in especially Cu-Nb reinforced Cu stabilized Nb3Sn wire. In an attempt to understand the effec

Steady and Unsteady Current Modes and Thermal Runaway Conditions of High-Tc Composite Superconductors

Autor: Gen Nishijima, K. Watanabe, Satoshi Awaji, V.R. Romanovskii

Publikováno v: IEEE Transactions on Applied Superconductivity. 17(2):3133-3136

Transport current properties of the steady and unsteady operating modes and thermal runaway conditions of the Ag-sheathed Bi2Sr2CaCu2O8 composite superconductors are theoretically studied in DC magnetic fields. It is shown that the temperature of a c
