Reinforcement materials for high field magnets

The material programs related to the fabrication of various magnets include the selection and characterization of reinforcement materials and the development of fabrication routes for these materials. Stainless steels (SS), Elgiloy and MP35N were studied for their potential use as the reinforcement materials. The fabrication routes include the annealing, deformation and aging. The SS materials were tested in deformed and annealed conditions, whereas Elgiloy and MP35N were tested in aged conditions because of the strengthening effects of aging. Examination of the microstructure and mechanical properties of these materials reveals that the microstructures developed during the fabrication influence the mechanical response of the materials to the Lorentz force and other external forces. The strengthening mechanisms of these materials have been considered in detail and related to the possible mechanical response to the Lorentz forces.
