Book excerpt: ABSTRACT: Out of the two most used materials (Nb3Sn and NbTi) for superconducting magnets, the Nb3Sn type conductor has been shown to have higher critical properties and capable to generate fields higher than 8 tesla. However, the superconducting properties of Nb3Sn are highly strain sensitive and mechanically weak. To fully utilize the high critical current of Nb3Sn conductor, strengthened Nb3Sn wires are required. In this research a review and comparison of various approaches to strengthen Nb3Sn supperconductors have been carried out. The dispersion strengthening approach was selected as a major strengthening method. Here, a detailed study on the fabrication and characterization of alumina nanoparticle dispersion strengthened Nb3Sn wires is presented. Both the mechanical and superconducting properties were concurrently improved by using this method.
