Invited Oral

Quantitative bending strain property of critical current is inevitable for designing spiral and pancake coils in practical magnets and other SC applications. The present study is to establish a quantitative measuring method on the bending strain dependence of Ic for REBCO tapes. Practical tapes have two types of twinned structure. They are characterized as having <100> and <110> orientations...

Invited Oral

So far, the round-robin-test has been proposed and successfully performed to establish the standard of the test method for measuring the mechanical properties and the critical current of superconducting properties of various composite superconducting wires, and has contributed significantly to the establishment of international standards (IS). With the development of high-performance HTS wires...

334. M2Or3H-04: [Invited] Review on the investigations of uniaxial stress susceptibility of pre-over pressure reacted Bi-2212 round wires for fusion high-field magnet application

Invited Oral

Bi-2212, a promising cuprate High Temperature Superconductor (HTS), is the only one capable of being formed into round wires. It has a high upper critical magnetic field and critical current density, making it an ideal choice for use in the Cable-In-Conduit Conductors (CICC) of the China Fusion Engineering Test Reactor (CFETR)'s Central Solenoid coils. The Over-Pressure (OP) heat-treatment can...

456. M2Or3H-05: [Invited] Compressive bending property of BSCCO tapes

Shutaro Machiya (Daido university)

Invited Oral

BSCCO and REBCO tapes have a rectangular cross section, making them suitable for coil applications and power transmission cables. In short, the advantage is that it is easy to bend, but strain due to bending is inevitable. and in BSCCO there is a difference in strength between the two. Compression test results with a bending jig showed that it was more susceptible to compressive strain than...
