Description
Technical field
The present invention relates to a kind of methods preparing iron-based superconducting composite strip.
Background technology
Breakthrough of the high temperature superconducting materia in forceful electric power application field depends on superconductor and superconducting line, band process work
The development of skill.The iron-based superconducting material found in 2008 is because it has a high upper critical field simultaneously, less anisotropy and higher
The characteristics such as superconducting transition temperature and evoked the research boom in worldwide, be expected in hyperconductive cable, transformer, superconducting magnetic
Body etc. is used widely.Currently, it is metallic sheath tube method (PIT to prepare the more mature method of iron-based superconducting line, band
Method).The ripe powder of synthesis iron base superconduction under the high temperature conditions first, then ripe powder is fitted into metal tube, then the metal tube is carried out
A series of mechanical processings, finally by being thermally treated resulting in iron-based superconducting line, strip product.Since there are weak in iron-based superconducting material
Joint efficiency, therefore the general method using rolling or compacting prepares iron-based superconducting tape, improves texture degree to improve current-carrying
Performance.Since silver has iron-based superconducting material enough chemical reaction inertia, and it also has the good capacity of heat transmission and prolongs
Malleability, therefore silver-colored pipe is typically chosen in PIT methods as sheath material.However, can a kind of superconductor industrially extensive
Higher current density can be carried using it is depended not only on, additionally depends on whether it has very high tensile strength, if
Smaller radius can be bent to and keep high current simultaneously.Although silver-colored jacket has the advantages that above-mentioned, its mechanical strength is very
It is weak.Studies have shown that the irreversible stress value σ of silver-colored jacket iron-based superconducting tapeirrOnly 35Mpa
[Supercond.Sci.Tech.28,035007 (2015)], are easy under high-intensity magnetic field due to being occurred not by forceful electric power magnetic force
Reversible destruction, therefore the electric power application such as be not suitable for superconducting coil, hyperconductive cable.In addition, by swaging, drawing, rolling mill practice
There are a large amount of hole and crackles in the band core of the iron-based superconducting tape of preparation, seriously hinder superconducting critical current density Jc
Raising.Therefore, the consistency of iron-based superconducting core is improved, reducing hole and crackle becomes the primary study of iron-based superconducting line strips
Direction.Surpass currently, hot isostatic pressing method (HIP methods) and pressure sintering (HP methods) are respectively used to improve in iron-based superconducting wire and band
The consistency of core is led, superconducting critical current density of the band that wherein prepared by pressure sintering at 4.2K temperature and the magnetic fields 10T is more than
0.1MA/cm2, reach practical horizontal.However, the above method cannot be used for preparing the long line of superconduction, jacket machinery is not solved
The weak problem of intensity, is not suitable for large-scale industrial production and application.Therefore, it is necessary to the compound one layer of hardness of Ag jacket outer layers compared with
High jacket improves mechanical strength.At present generally complex superconducting wire strip is prepared using following two techniques：
1. inner layer sleeve and outer layer sleeve are first carried out compound, processing, multiple tube is obtained；Superconducting precursor powder is inserted again multiple
It closes in pipe and is machined and is heat-treated, obtain final wire strip, such as patent：200610114264.5
200710121109.0。
2. first inserting front axle shell in inner tube, then the inner tube equipped with front axle shell is filled in outer layer sleeve, it is most laggard
Row mechanical processing obtains wire strip, such as patent：200910241918.4.
There are disadvantages for both the above technique：Since jacket is generally closed using softer Ag or Ag in iron-based superconducting line strips
Gold, and the hardness of outer layer jacket, ductility and internal layer jacket gap are larger, it is uneven to be easy to cause superconducting core for first compound reprocessing
Even disconnected core.Secondly, directly multiple tube is machined, it is difficult to form the superconducting core of highly-textured degree wherein.It is above to lack
Point will seriously affect the current-carrying performance of iron-based superconducting tape.
Therefore, it is necessary to develop a kind of iron-based recombination line, band preparation process, superconducting core consistency and critical electricity are being improved
While current density, the mechanical strength of wire rod, band is improved, production cost is reduced, makes that it is suitable for hyperconductive cable and superconducting magnetics
The preparation of body.
