摘要：
A method of production of a composite billet for a nuclear fuel cladding tube wherein a hollow inner billet of zirconium is inserted in a hollow outer billet of a nuclear fuel cladding material. Following insertion of a resilient member in the hollow inner billet, pressure is applied to the resilient member axially of the billets to force the inner billet against the outer billet, to produce a pressure bonding between an inner surface of the outer billet and an outer surface of the inner billet.
