Abstract
The transformation-processed Nb 3Al superconductor is a promising alternative for large-magnet applications; for example, for nuclear fusion magnets and accelerator magnets. In this review, some issues that should be solved for industrialization and their possible solutions are introduced. The review focuses on improvement of the longitudinal uniformity of the conductor, a facile stabilization method, minimization of magnetization compatible with the high critical current density and the characteristic microstructure of transformation-processed Nb 3Al superconductors related to the pinning property.
