う欠点があり、従って機械的性能の向上が必要である。Among these, Nb-Ti alloy is used for magnets 1 to 1 with a magnetic field of 9 Tesla or less, and Nb3Sn and V3Ga are used for magnets 1 to 15 with a magnetic field of 9 Tesla or less.
Nb3 is used in Tesla's high-field magnets.
Since Sn and V3Ga are compounds, they have the disadvantage that they are hard and bend, and cracks occur in the compounds due to strain, resulting in significant deterioration of superconducting properties such as critical magnetic field, critical current density, and critical temperature, and therefore improve mechanical performance. is necessary.
また、これらの化合物に代る高性能の高磁界用超電導材
料が望まれている。There is also a desire for high-performance superconducting materials for high magnetic fields to replace these compounds.

能劣化のない超電導線を得るべく検討の結果、得られた
ものである。<Means for solving the problems> In view of the above, the present invention is based on an Nb-Ti alloy or an Nb-Ti alloy.
b3Sn, V3 This was obtained as a result of studies aimed at obtaining a superconducting wire without deterioration of performance due to strain instead of the Ga compound.
Ｖ２Ｈｆは臨界磁界が２２テスラでＮｂ３Ｓｎと同等で
あるが、中性子照射やひずみに対する劣化が小ざいこと
から、高磁界用材料として有望である。V2Hf has a critical magnetic field of 22 Tesla, which is equivalent to Nb3Sn, but it is promising as a material for high magnetic fields because it shows little deterioration due to neutron irradiation and strain.

The reason for setting X in the range of 25 to 40 in X atom%T is that if X is less than 25, it will be hard and brittle, and the workability will be poor.
This is because when the value is 40 or more, precipitation of v2F(f) is small and the superconducting properties are not good.

Heat treatment at 800°C or higher after processing a supersaturated solid solution ingot obtained after rapid solidification of Ti into a wire or thin plate is because the precipitation rate is slow below 800°C, requiring a long heat treatment, which increases the cost. This is because it becomes high.
