Fatigue and Stress Effects in NbTi and Nb3Sn Multifilamentary Superconductors

  • Chapter
Advances in Cryogenic Engineering

Part of the book series: Advances in Cryogenic Engineering ((ACRE,volume 24))

Abstract

Recent measurements have indicated a degradation of the critical current of NbTi [1] and Nb3Sn [2–6] multifilamentary composites under static tensile stress. In this paper these static stress results are summarized and preliminary measurements of the effects of cyclic stress on the critical current, mechanical strength, and stability of these superconductors are reported.

Invited paper.
