The economical manufacture of fully stabilized multifilamentary Nb3Al wire is needed to produce very high magnetic coils for nuclear magnetic resonance, accelerators, and research magnets. Such a wire is required for future high-energy accelerator magnets because Nb3Al maintains a high critical current density in fields in the 10-25 tesla range. This project will develop a low cost manufacturing process for a near-net shape-Nb3Al wire. A rapid quench process will be used to manufacture precursor wire in 1 km lengths. Phase I will focus on producing near-net-shape powder metallurgy precursor wires, designing high speed wire diameter reduction machines, and developing methods for putting a copper stabilizer on the Nb3Al wire after the rapid quench process.
Commercial Applications and Other Benefits as described by the awardee: A low cost, high magnetic field wire that enables magnets in the 10-25 tesla range should find applications in nuclear magnetic resonance for medical and biological purposes. It should also enable the next generation of accelerators for the high energy physics community.
