Superconductivity - Part 6: Mechanical properties measurement - Room temperature tensile test of Cu/Nb-Ti composite superconductors (IEC 61788-6:2011) (english version)
This part of IEC 61788 covers a test method detailing the tensile test procedures to be carried
out on Cu/Nb-Ti superconductive composite wires at room temperature.
This test is used to measure modulus of elasticity, 0,2 % proof strength of the composite due
to yielding of the copper component, and tensile strength.
The value for percentage elongation after fracture and the second type of 0,2 % proof
strength due to yielding of the Nb-Ti component serves only as a reference (see Clauses A.1
and A.2).
The sample covered by this test procedure has a round or rectangular cross-section with an
area of 0,15 mm2 to 2 mm2 and a copper to superconductor volume ratio of 1,0 to 8,0 and
without the insulating coating.
