Definitions
- the invention relates to a semi-finished product based on nickel with a recrystallization cube texture and a method for its production.
- the semi-finished product can be used, for example, as a base for physico-chemical coatings with a high degree of microstructural orientation.
- Such documents are suitable, for example, as substrates for ceramic coatings, as are used in the field of high-temperature superconductivity. In this case they are used in superconducting magnets, transformers, motors, tomographs or superconducting current paths.
- Buffer layers and ceramic superconductor layers are used
- Substrate material largely depends on the achievable degree of
- Textured semi-finished products for the production of high-temperature superconductors consist of Ni-Cr, Ni-Cr-V, Ni-Cu and similar alloys (US Pat. No. 5,964,966; US Pat. No. 6,106,615).
- Ni alloys with Mo and W (DE 100 05 861 Cl) are also known for these purposes.
- Ni strips tend to form grain boundary trenches during recrystallization heat treatment, especially at higher temperatures (800 to 1150 ° C) , the grain boundary trenches can considerably hinder the formation of a high-grade biaxial cube texture, - substrate material with grain boundary trenches is not very suitable as a base for epitaxial layer deposits, for example for buffer layers and superconductor layers.
- the invention is based on the object of developing a semifinished product based on nickel which has improved performance properties for use as a base for physico-chemical coatings with a high degree of microstructural orientation.
- the semi-finished product should have a higher-grade and thermally more stable cube texture and the formation of grain boundary trenches should be avoided as far as possible. Included in this task is the development of a process for the production of this semi-finished product.
- the material of the semi-finished product contains an Ag addition in the microalloy range, the Ag addition being a maximum of 0.3 atomic%.
- the Ni alloy can contain Mo and / or W as alloying elements.
- a cube-textured NiO layer with a texture fraction of> 90% can be present on the semi-finished product.
- This layer is suitable as a diffusion barrier and enables high-quality coatings to be produced, in particular under oxidizing conditions.
- the formation of a high-grade cube texture is promoted and the thermal formation of grain boundary trenches on the Ni surface of the semi-finished product is hindered.
- the Ag additive enables the growth of a highly cube-textured NiO layer on the semi-finished product.
- the process according to the invention for producing the semi-finished product is characterized in that first a semi-finished product is produced by melt metallurgy or powder metallurgy, including mechanical alloying, which consists of technically pure Ni or a Ni alloy containing an Ag additive in the microalloy range which is at most 0.3 atomic%. Then this semi-finished product is processed into strip or flat wire by means of hot forming with subsequent high-grade cold forming of> 80% thickness reduction. Finally, this semi-finished product is subjected to a recrystallizing annealing in order to achieve a cube texture.
- the semi-finished product thus produced can be heat-treated according to the invention for the purpose of growing a cube-textured NiO layer in an oxidizing atmosphere.
- the semifinished product can be used as a base for physico-chemical coatings with a high degree of microstructural alignment, in particular for production wire or ribbon-shaped high-temperature superconductors are used.
- Example 1 Technically pure nickel with a purity of 99.9 atom%
- Ni is poured into a mold with the addition of 0.01 atomic% of silver.
- the ingot is rolled at 1000 ° C to the square dimension (22x22) mm 2 , annealed to homogenize and quenched.
- the square material is then machined to obtain a flawless surface for the subsequent cold forming by rolling.
- the cold rolling is carried out with a rolling degree of more than 80% thickness reduction, in this case with 99.6%.
- the resulting nickel strip has a thickness of 80 ⁇ m and is highly roll-textured. It is then subjected to a 30-minute annealing treatment in a non-oxidizing gas atmosphere at 550 ° C.
- Ni is melted with alloying of 0.01 atomic% silver in a vacuum induction furnace and poured into a mold.
- the ingot is rolled at 1000 ° C to the square dimension (22x22) mm 2 , annealed to homogenize and quenched.
- the square material is then machined to create a flawless surface for the subsequent cold forming To get rollers.
- the cold rolling is carried out with a rolling degree of more than 80% thickness reduction, in this case with 99.6%.
- the resulting nickel strip has a thickness of 80 ⁇ m and is highly roll-textured. It is then subjected to a 30-minute annealing treatment in a reducing gas atmosphere at 550 ° C.
- the result is an almost complete recrystallization cube texture.
- the strip is then subjected to a 5-minute oxidation in pure oxygen gas at 1150 ° C.
- the resulting nickel oxide layer has a cube texture in which 97% of the grains have the cube layer. This texture is rotated 45 ° with respect to the texture of the nickel band (see Fig. 2).
- the FWHM value of the (III) pole is 6.2 °.
- the cold rolling is carried out starting from a dimension of (10x10) mm 2 up to the finished dimension of 80 ⁇ m thickness.
- the edge areas of the tape are cut off and discarded.
- the nickel strip obtained is then first subjected to a 30-minute annealing treatment at 550 ° C. for recrystallization in a reducing atmosphere.
- the strip is then treated in a second annealing for 8 minutes at 1100 ° C in a reducing atmosphere in order to establish a thermally highly resilient cube layer.
- Table 1 shows, with the values of substrates No. 5 and 6, the positive influence of the Ag addition according to the invention on the FWHM (111) values in comparison with the prior art (substrates No. 1 to 4).
