説明:

Mechanical properties of such ultra-thin Nb3Sn wires were evaluated to determine the cabling parameters and mechanical analysis of twisted cables. Tensile tests were performed at room temperature for 0.05 mm-thick Nb3Sn wires before and after heat treatment for the first time. Basic mechanical parameters such as
0.2% proof strength and fracture strength were evaluated from a stress–strain curve. Young’s modulus of such a thin wire was determined from unlading and reloading slopes of a load–stroke curve for the specimens with different gauge lengths. Fracture strain was estimated without using extensometers and strain gauges by correcting for machine deformation. Based on these results, we concluded that a simple technique to measure stress–strain curves for ultra-thin Nb3Sn wires was able to be established.
