Nb3Al belong to A15 superconductors as well as Nb3Sn,has been planned to use in diverse research programs,such as ITER Central Solenoid Model Coil.Compared with Nb3Sn,Nb3Al superconductor is relatively insensitive to stress and strain,can endure the stronger Lorentz force of high field.However,the manufacture technical of Nb3Al superconducting wire is relatively difficult and complex,special techniques such as rapid-heating/rapid-quenching (RHQ) technique are required.Meanwhile,the required temperature of Nb3Al transforming into superconducting phase is above 800 degrees Celsius,which brings some certain challenges for the heat treatment and other magnet manufacturing technologies.
