Abstract
A method for producing a metal film from an over 50% nickel alloy melts more than one ton of the alloy in a furnace, followed by VOD or VLF system treatment, then pouring off to form a pre-product, followed by re-melting by VAR and/or ESU. The pre-product is annealed 1-300 hours between 800 and 1350° C. under air or protection gas, then hot-formed between 1300 and 600° C., such that the pre-product then has 1-100 mm thickness after the forming and is not recrystallized, recovered, and/or (dynamically) recrystallized having a grain size below 300 μm. The pre-product is pickled, then cold-formed to produce a film having 10-600 μm end thickness and a deformation ratio greater than 90%. The film is cut into 5-300 mm strips annealed 1 second to 5 hours under protection gas between 600 and 1200° C. in a continuous furnace, then recrystallized to have a high cubic texture proportion.
