Raw material selection: Sponge zirconium (nuclear grade) or industrial grade zirconium ingots are used, with a purity of ≥99.2%.
Melting and casting: Impurities are removed by vacuum consumable arc melting (VAR) or electron beam melting (EB).
Hot processing: Forging and rolling to the target thickness, the temperature (800-1200°C) must be controlled during the process to avoid grain coarsening.
Cold processing: Reduce the thickness through multiple cold rolling, and eliminate work hardening with intermediate annealing (600-800°C).
Surface treatment: Pickling to remove oxide scale, polishing to improve surface finish.
