The application belongs to the technical field of superconducting materials, and discloses a high-performance MgB2 superconducting wire and a preparation method thereof. The method comprises the following steps: firstly, uniformly mixing nano-Mg alloy powder and B powder in an inert gas atmosphere according to an atomic number ratio of Mg:B=1:2; secondly, compounding a high-purity Nb rod, a CuNi alloy tube and an oxygen-free Cu tube into an Nb / CuNi / Cu alloy rod, processing deep holes, and then making a single-core wire by loading the mixed powder; thirdly, assembling the single-core wire into a Monel alloy tube, processing into a multi-core composite wire, and obtaining the high-performance MgB2 superconducting wire through high-temperature phase formation heat treatment. The metal elements in the nano-Mg alloy powder can generate metal borides, and the CuNi alloy has both constraint and barrier effects, so that the MgB2 grains of the wire are refined, the connectivity between the grains is improved, and the current-carrying performance is improved.

The utility model discloses a kind of for measuring monel alloy corrosion depth's ultrasonic detector, it is related to monel alloy measurement technical field, including first adjusting frame, second adjusting frame and detection component, the top vertical connection of first adjusting frame is equipped with second adjusting frame, the detection component is connected in one side of second adjusting frame.The utility model can effectively reduce the influence of external vibration on detection accuracy in the measurement process by setting first adjusting frame, moving platform is driven first screw rod to realize horizontal displacement by first servo motor, by setting second adjusting frame, lifting frame is accurately vertically moved along second screw rod under the drive of second servo motor, and the three-dimensional space adjusting system is formed by the cooperation of the two, so that detection component can accurately cover alloy surface any corrosion area, and the ultrasonic detection main body of detection component is realized angle fine adjustment by ratchet shaft.
