Show Abstract
A multilayer wire‐wound pulsed field magnet was fabricated using a new metal‐matrix microcomposite Cu/Nb conductor. The 0.5‐in.‐i.d. magnet used square cross‐section Cu/Nb wire, precompressed in a hardened steel container and cooled to 77 K, to generate 68.4±1 T for a 5.6‐ms half‐period. The maximum field was generated using a 100‐kJ, 4‐kV capacitor bank of the Francis Bitter National Magnet Laboratory pulsed field facility. The Cu/Nb composite had an ultimate tensile strength of 180 ksi at 77 K and 140 ksi at 293 K. These new microcomposites have exceptional strength, electrical, and thermomechanical properties for very high stress applications.
