摘要： A nickel-based semifinished product has a cube recrystallization texture and the semifinished product can e.g. be used as a support for physicochemical coatings having a highly microstructured orientation. Such supports are e.g. suitable as substrates for ceramic coatings such as are used in the field of high-temperature supraconductivity. In this case, the product is used in supraconducting magnets, transformers, motors, tomographs and supraconducting current paths. There is provided a nickel-based semifinished product that has improved performance characteristics when used as a support for physicochemical coatings having a highly microstructured orientation. Especially the semifinished product should have a higher-grade, thermally more stable cube texture while substantially preventing the formation of grain boundary grooving. For this purpose, Ag in the microalloy range is added to the material of the semifinished product, the added Ag being not more than 0.3 atomic percent. The inventive semifinished product is e.g. suitable as a support for physicochemical coatings having a highly microstructured orientation.

摘要： 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. For this purpose, the inventive method consists in producing an initial semi-finished product by means of a fusion or powder metallurgy process including mechanical alloys, wherein the semi-finished product comprises a technically pure Ni or the alloy thereof containing an Ag additive in a microalloy range which is equal to or greater than 10 atom ppm and is equal to or less than 1000 atom ppm, in shaping the initial semi-finished product in the form of a strip or flat wire by hot- and cold forming processes with a thickness reduction >50% associated with an intermediate measuring. During the intermediate measuring, the semi-finished product is softened by annealing at a temperature ranging from 500 to 850° C., wherein the high temperatures are used for high Ag contents, and is subsequently quenched. Afterwards, the semi-finished product is exposed to the 80% cold shaping. The inventive method also consists in carrying out a recrystallization annealing treatment in such a way that the entire cubic texture is obtainable. The inventive semi-finished product is used in the form of a base for physical-chemical coatings provided with a high-quality intense microstructural orientation and for producing a high-temperature superconductor in the form of a flat wire or strip.

摘要： 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 εg≧75% or a logarithmic deformation φg≧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.

摘要： A method for producing metallic strips having a high-grade cube texture based on nickel, copper, aluminum, silver or alloys of these metals including austenitic iron-nickel alloys makes it possible to obtain, during a subsequent annealing process and with lower total degrees of forming, a recrystallization cube layer of a quality equal to that of one obtained using customary roll forming and produces a better quality cube texture with comparable total degrees of forming. To this end, a forming method is provided during which the materials are formed by cold drawing before their recrystallization annealing thereby rendering them high-grade. The tools used for this include: a) non-driven roll devices with an axially parallel flat pair of rolls or turk's head arrangements with two pairs of rolls or; b) fixed drawing jaws that are slanted toward one another. The strips produced according to the invention can be used, for example, as a coating support for producing strip-shaped high-temperature superconductors.
