[0002] Niobium-titanium alloy refers to an alloy composed of metal niobium and metal titanium. They are important alloy-type superconducting materials with a superconducting transition temperature of 8 to 10K. Adding other elements can further improve the superconducting performance. Titanium exists in the alloy as a solid solution. The alloy is sintered with mixed powder and electrodes composed of niobium sheets and titanium sheets through a vacuum consumable arc furnace or electron beam melting for several times to form an alloy ingot.
