Niobium-Titanium: Workhorse Supermagnet Material - .

The high critical magnetic field for the niobium-titanium alloys, 14.5 tesla, was a clue that they might after all be useful for supermagnet windings despite the discouraging critical- supercurrent-density results obtained earlier at both BTL and AI.
