IEC 61788-19:2013涵盖了一种试验方法，详细说明了在室温下对反应后的Cu/Nb3Sn复合超导导线进行拉伸试验的程序。本试验的目的是测量弹性模量，并根据应力-应变曲线确定因铜和铜锡成分屈服而产生的复合材料的验证强度。此外，弹性极限、抗拉强度和断裂后伸长率可通过本方法确定，但它们被视为可选量，因为根据国际循环试验，已报告弹性极限和断裂后伸长率的测量量存在重大不确定性。本试验程序涵盖的样品应具有裸露的圆形或矩形横截面，其面积在0.15 mm2和2.0 mm2之间，铜与非铜的体积比为0.2到1.5，且不应具有绝缘。 关键词:超导电性，力学性能

IEC 61788-19:2013 covers a test method detailing the tensile test procedures to be carried out on reacted Cu/Nb3Sn composite superconducting wires at room temperature. The object of this test is to measure the modulus of elasticity and to determine the proof strength of the composite due to yielding of the copper and the copper tin components from the stress versus strain curve. Furthermore, the elastic limit, the tensile strength, and the elongation after fracture can be determined by means of the present method, but they are treated as optional quantities because the measured quantities of the elastic limit and the elongation after fracture have been reported to be subject to significant uncertainties according to the international round robin test. The sample covered by this test procedure should have a bare round or rectangular cross-section with an area between 0,15 mm2 and 2,0 mm2 and a copper to non-copper volume ratio of 0,2 to 1,5 and should have no insulation.
