Mechanical properties measurement - Tensile test of practical REBCO and BSCCO composite superconductors at cryogenic temperatures
Abstract
This part of IEC 61788 covers a test method detailing the tensile test procedures to be carried out on practical REBCO and BSCCO superconductive composite tapes at cryogenic temperatures. This test is used to measure the modulus of elasticity and 0,2 % proof strength. The values for elastic limit, fracture strength and percentage elongation after fracture shall serve only as a reference. The sample covered by this test procedure for REBCO wires should have a rectangular cross-section with an area of 0,3 mm2 to 4,0 mm2 (corresponding to the tapes with width of 2,0 mm to 12,5 mm and thickness of 0,15 mm to 0,4 mm). The sample covered by this test procedure for BSCCO wires should have rectangular cross -section with an area of 0,3 mm2 to 2,0 mm2 (corresponding to the tape-shaped wires with width of 2,0 mm to 5,0 mm and thickness of 0,16 mm to 0,4 mm).
