Definitions

  • the invention relates to a process for the production of nickel-based semi-finished products in strip or flat wire form with a recrystallization cube texture and the use of the semifinished product produced.
  • the semifinished product can be used in particular as a substrate for physico-chemical coatings with a high degree of microstructural alignment.
  • Such supports are suitable, for example, as substrates for ceramic coatings as used in the field of high temperature superconductivity. In this case, they are used in superconducting magnets, transformers, motors, tomographs or superconducting current paths.
  • Ni alloys with Mo and W DE 100 05 861 C1 . It has also been proposed to add to such Ni alloys up to a maximum of 0.3 atom% Ag ( DE 103 42 965.4 ).
  • the semi-finished product should have an elongated grain shape with stable cube texture, and the expanded grain should remain intact even after further thermal treatment at high temperatures for the purpose of oxide layer growth.
  • the method according to the invention is characterized in that initially a starting semi-finished product is produced by fusion metallurgy or powder metallurgy involving mechanical alloying, which consists of technically pure Ni or a Ni alloy, wherein an Ag addition in the microalloying range of at least 10 atomic ppm and a maximum of 1000 atomic ppm is contained.
  • This starting semifinished product is processed by means of a hot forming with subsequent cold working of> 50% thickness reduction to tape or flat wire with an intermediate dimension.
  • the semi-finished product is annealed in the temperature range between 500 ° C and 850 ° C annealed, the higher temperatures are used for the higher Ag contents, and then quenched. Subsequently, this intermediate is highly> 80% cold formed. Finally, a recrystallizing annealing treatment to achieve a complete cube texture is performed.
  • the final recrystallization annealing treatment is carried out at temperatures of 500 ° C to 1200 ° C, preferably at 850 ° C, depending on the alloy content in the nickel.
  • the semifinished product may advantageously be heat treated after or during the recrystallizing annealing for the purpose of growing a cube-textured NiO layer having a texture content of> 90% in an oxidizing atmosphere.
  • Ni alloy is used for the starting semi-finished product, which still contains Mo and / or W as alloying elements in addition to the Ag addition.
  • the formation of a high-grade cube texture is favored.
  • the expanded metal strip allows the growth of a highly cube textured NiO layer, which also has elongated grains.
  • the semifinished product can be used as a substrate for physico-chemical coatings with a high degree of microstructural orientation, in particular for producing wire-shaped or ribbon-shaped high-temperature superconductors.
  • the resulting nickel oxide layer has a structure with elongated grains, whose proportion with cube position is 97% ( Fig. 4 ). The proportion of small-angle grain boundaries is 96%. This texture is rotated 45 ° from the texture of the nickel strip.
  • the resulting nickel strip is then first subjected at 850 ° C a 30-minute annealing for recrystallization in a reducing atmosphere. Thereafter, the strip is treated in a second annealing for 8 minutes at 1150 ° C in a reducing atmosphere to set a thermally highly resilient cube layer.
