Non-destructive pulsed field CuAg-solenoids

摘要: Abstract Ultra strong CuAg-based conductor materials have been developed and tested in pulsed high-field magnets. The yield strength of a cold deformed CuAgZr material has assessed on the basis different hardening mechanisms: solid solution, grain boundary, precipitation dislocation hardening. experimental value for when transferred to shear by Schmid’s law is between linear quadratic superposition individual critical stresses hence found be good agreement with theoretical predictions. shows an ultimate tensile more than 1.1 GPa at room temperature (yield about 1 GPa, plastic strain: 0.7%). Based properties new coil designed tested. features additional internal reinforcement layers, which are optimised using computer simulations. In combination refined simulation techniques, such as finite element modelling, significant progress was made concerning use these magnet applications. generated field 66 T without being destroyed, constitutes record Clarendon Laboratory Oxford, UK.
