  • Patent number: 8465605
    Abstract: A nickel-based semi-finished product, for making a high-temperature superconductor, embodied in the form of a strip or flat wire is produced and used as a base for physical-chemical coatings provided with a high-quality intense microstructural orientation. The semi-finished product has an improved granular structure provided with a stable cube texture. A fusion or powder metallurgy process including mechanical alloys makes a semi-finished product including a technically pure Ni or Ni alloy containing an Ag additive in a specified microalloy range. The product is shaped as a strip or flat wire by hot- and cold forming processes with a thickness reduction >50% The product is softened by annealing at 500 to 850° C. and is subsequently quenched. Afterwards, the product is exposed to the 80% cold shaping. A recrystallization annealing treatment is carried out to obtain an entire cubic texture.

  • Publication number: 20090008000
    Abstract: The invention relates to a method for producing and using a nickel-based semi-finished product embodied in the form of a strip or flat wire. The aim of the invention is to develop a method for producing a nickel-based semi-finished product which exhibits improved performance characteristics for the use in the form of a base for physical-chemical coatings provided with a high-quality intense microstructural orientation. The semi-finished product should have an improved granular structure provided with a stable cube texture.

  • Publication number: 20070234542
    Abstract: Method for producing metallic flat wires or strips with a cube texture that can be used, for example, as a base for physical-chemical coatings. The products can be produced after the last forming step in their finished width without further processing of the edges. The method includes processing a material based on nickel, copper, gold, or silver into a wire by a cold drawing method, achieving a total cross-sectional reduction ?g?75% or a logarithmic deformation ?g?1.4, and the wire is then further processed by further forming and annealing methods into a flat wire or a strip with a cube texture and having a width that can be adjusted in a defined manner.
