Have the Ni-based work piece of recrystallize cubic texture structure and its manufacture method and application
The present invention relates to a place and have the Ni-based work piece of recrystallize cubic texture (upright line) structure and its manufacture method.
These work piece for example can be suitable for the substrate used as the physical chemistry coating with high microstructure orientation, this substrate for example can be used as the base of ceramic plated layer, they obtain in the high-temperature superconductor field to use, and purposes in this case has superconducting magnet, transformer, motor, X-ray chromatography to take pictures or the supercurrent conducting path.
Known polycrystalline metal such as nickel, copper and aluminium with three-dimensional face-centred lattice, formerly after rolling powerful cold deformation, the recrystallize that carries out can form the clear texture structure (G.Wassermann:Texturen metallischer werkstoffe springer, Berlin 1939) with cube position immediately.Carry out the sheet metal strip of texture structureization, particularly nickel strap material in this way, also can be used as the substrate (US5,741,377) of metal plating, ceramic buffer layer and ceramic superconductivity layer.Whether this sheet metal strip is suitable for depending on the veining degree that reached in stratification technological work temperature range and the stability of texture structure as base material.
The work piece of the texture structureization of the high-temperature superconductor of manufacturing Ni-Cr, Ni-Cr-V, Ni-Cu and similar alloy have been (US5,964 of knowing, 966; US6,106,615).
For the Ni-alloy that contains Mo and W of this application purpose also is known (DE10005861C1).
Known work in-process have following shortcoming:
-nickel has the trend of strong formation coarse-grained structure after cold machine-shaping and recrystallization annealing, this is deleterious to realizing that height founds the line structure,
The Ni band of-cold machine-shaping particularly has the trend of strong formation crystal boundary ditch at high temperature (800 to 1150 ℃) when recrystallize one thermal treatment,
-crystal boundary ditch can seriously hinder the formation of the upright line structure of height amphicheirality,
-base material with crystal boundary ditch not too is suitable as epitaxially grown settled layer, for example buffer layer and superconducting layer.
Task of the present invention is the Ni-based work piece of exploitation, it is as the substrate of the physical chemistry coating with height microstructure orientation, and can improve its application performance, these work piece show that especially its heat-staple height founds the line structure, and can prevent the formation of crystal boundary ditch greatly.In this project, also comprise a kind of manufacture method of developing this work piece.
The solution of this task is that the material of these work piece contains interpolation silver in the microalloy district, and basic content is 0.3 atom % to the maximum.
By the autotelic project organization of the present invention is the nickelalloy that can contain Alloy Elements Mo and/or W.
By the present invention on these work piece, can contain＞90% have the structurized NiO-layer of upright line that texture is formed, this tunic can be used as diffusion barrier and can especially produce high-quality coating under oxidizing condition.
When having, can promote highly to stand the formation of line structure, and on the nickel surface of work piece, avoid producing the crystal boundary ditch that in addition, additional silver can also make the growth of the NiO-layer that highly possesses upright line structure on work piece owing to hot by interpolation of the present invention silver.
Make the processing method of work piece by the present invention, it is characterized in that, earlier with fusion metallurgy or powder metallurgic method, comprise the mechanical process manufacturing alloy by way of making work piece, it is contained in the microalloy district by technical grade pure nickel or nickelalloy, and interpolation is silver-colored to be formed, its silver-colored maximum level is 0.3 atom %, then, with these work piece by a heat processing and forming, be processed into the band or the flat filament of reduced down in thickness＞80% immediately again with powerful cold machine-shaping method, at last these work piece are carried out recrystallization annealing, and obtain the cubic texture structure.
In the recrystallization annealing process or afterwards, can the work piece of preparation be made through thermal treatment in an oxidizing atmosphere by the present invention and reach the purpose that the structurized NiO-layer of upright line is grown up.
These work piece can be by the present invention as having the physical chemistry coating that the height micro-structural is orientated, especially for the substrate of making wire or banded high-temperature superconductor.
By the following examples the present invention is further illustrated.These demonstrate the present invention for example and have done successful test, a part of test-results collect in Fig. 1 and Fig. 2 and under tabulate in 1.
