METHOD OF PRODUCING A ZIRCONIUM ALLOY SEMI-FINISHED PRODUCT FOR THE PRODUCTION OF AN ELONGATED PRODUCT AND USE THEREOF

摘要

The invention relates to a method of producing a zirconium alloy semi-finished product for the production of an elongated product and to the use thereof. According to the invention, a large ingot (1) is produced by means of zirconium alloy casting and, subsequently, the ingot is forged in order to produce the semi-finished product (3) in two steps. The first ingot (1) forging step is performed at a temperature at which the zirconium alloy is in a state comprising crystalline phases A and B, for example, said forging temperature can be between 850 DEG C and 950 DEG C.
