Mechanical behaviour of high nitrogen stainless steel reinforced conductor for use in pulsed high field magnets at cryogenic temperature

Abstract:

The use of copper - high nitrogen stainless steel macrocomposites for applications such as pulsed high magnetic field coils is demonstrated in this contribution. The macrocomposite reveal an enhancement of up to 40% in strength when cooling from 300 K down to liquid nitrogen temperature. An ultimate tensile strength of 1.53 ± 0.017 GPa is reached with a 3 mm × 2 mm wire with 52 vol.-% Cu and a logarithmic drawing strain of η = 2.8 at liquid nitrogen temperature. Compared to the low nitrogen s...
