Latest Patents

Selbmann holds a patent for a "Method for the production and use of semi-finished products on the basis of nickel, having a recrystallization cube texture." This patent describes a nickel-based semi-finished product designed for creating high-temperature superconductors. The product is produced in the form of a strip or flat wire and serves as a base for high-quality physical-chemical coatings. The semi-finished product features an improved granular structure with a stable cube texture, achieved through a fusion or powder metallurgy process that includes mechanical alloys. The process results in a technically pure nickel or nickel alloy with an added silver component. The shaping of the product involves hot- and cold-forming processes, with a thickness reduction exceeding 50%. The product undergoes annealing at temperatures between 500 to 850°C, followed by quenching and 80% cold shaping. A recrystallization annealing treatment is then performed to achieve a complete cubic texture.
