Description
Technical field
The invention belongs to the high temperature superconducting materia preparing technical field, relate to a kind of preparation method of used for coating conductor alloy base band, particularly relate to a kind of preparation method of nickel-tungsten alloy base-band for coated conductor.
Background technology
Compare with the Bi series superconducting material, the Y series superconducting material has high current capacity under higher irreversible (Birr) and the high temperature highfield, is the unique high temperature superconducting materia that can realize the forceful electric power application at liquid nitrogen temperature.The subject matter that restriction Y series superconducting material is used is the weak connection that the high-angle boundary of intergranular causes, must reduce and eliminate high-angle boundary and make it to form strong-texture to improve the current-carrying performance.At present, there are two kinds of approach in Y frenulum material, to form strong-texture, the one, adopt ion beam assisted depositing (IBAD) technology, this technology is by depositing the oxide that one deck has biaxial texture earlier on the nickel-base alloy base band, depositing the YBCO film on this basis.Another method is rolling auxiliary biaxial texture base band (RABiTS) method, and this method is the base band that obtains having strong cubic texture by hot process for machining, on this basis by epitaxy deposited barrier layers and YBCO superconducting layer.The long base band of flexibility with cubic texture is the basis of practical coating conductor preparation.
Nickel and nickel alloy material are to adopt the preparation of RABiTS technology to have the preferred material of the flexible base band of cubic texture, and it can form strong cubic texture by big cold working rate and recrystallization annealing.Its non-oxidizability and little displacement angle allow barrier layer and superconducting layer epitaxial growth.People have obtained critical current density above 10 on nickel-base strip
6A/cm
2The YBCO film.In order further to improve the engineering current density (Je) of coating conductor, thickness that must the attenuate base band because the lower tensile strength of Ni-based band, is restricted adopting continuous roller to prepare in the belt material of high temperature superconduct to the roller depositing operation.Simultaneously, because the ferromagnetism of nickel can cause the magnetic hystersis loss of AC applications floating coat conductor, influenced the practical application of coating conductor.For this reason, people improve the intensity of metallic nickel base band by alloying, and reduce its magnetic.Studies show that Cr, the V of interpolation 5at% and three times of intensity raisings and strong cubic texture that W can make base band do not lose.Further result of study shows, the Cr and the V that add 10at% can make Curie temperature be lower than 77K, significantly reduce the magnetic hystersis loss of coating conductor.But, adding Cr and V and cause base band surface when crystallization heat is handled again the oxide of Cr and V to occur easily, this will hinder the epitaxial growth of barrier layer and superconducting layer.Therefore, research emphasis concentrates on nickel tungsten.Studies show that along with the increase of W content, the yield strength of base band can increase to 270MPa from 34MPa in the nickel tungsten, wherein the intensity of Ni-5at%W alloy can reach 165MP, and its Curie temperature drops to 335K by the 627K of pure nickel.When W content surpasses 5at%, though base band intensity can further will improve the sharpness of meeting appreciable impact cubic texture.Consider that from combination property the Ni-5at%W alloy is the preferable selection of coating conductor base band material.
