Influence of technological parameters on the mechanical properties of NT-50 superconducting multistrand conductors at low temperatures

1. A decrease in strand diameter to 0.1–0.2 μm leads to a steady change in elongation all the way to 4.2°K and to high values of strength. 2. With the same space factors and strand diameters, the influence of the method of production on the mechanical properties of the conductors is insignificant. 3. Heat treatment at 375°C of conductors with a space factor of ≈43% has practically no influence on their plasticity in the 20–300°K range in contrast to conductors with a space factor of ≈25%, which were considered in [1].
