摘要：
This paper describes the design and performance of a new tension test instrument for measuring stress-strain characteristics of a freestanding sample and critical current degradation of superconducting wires and tapes under variable tension and magnetic fields. The performance of the instrument has been tested at liquid nitrogen and liquid helium temperature up to a tensile force of 1000 N. Stress-strain and I-c-strain characteristics of advanced Bi-2223, Y-123 and MgB2 composite superconductors were measured. The results show the best electromechanical properties for the tapes mechanically reinforced by soldered stainless steel strips. MgB2 tape with a Ti-barrier and Monel sheath is less reinforced due to an apparent softening of these materials during the final annealing at 800 degrees C/30 min.
