Method for the production of a semi-finished product made of zirconium alloy for the production of a flat product and use thereof

摘要

A large ingot is produced by casting the zirconium alloy, then the ingot is forged to obtain the semi-finished product wherein the semi-finished product can be a slab for production of a flat product is produced from the large cast ingot in a single forging operation at a temperature at which the zirconium alloy is in a state comprising both the crystalline alpha and beta phases of the alloy.
