PROCEDURE FOR THE MANUFACTURE OF A CIRCONIO BASED ALLOY COMPONENT FOR USE IN THE NUCLEAR INDUSTRY.

摘要

Procedure for the production of an appropriate component to be subjected to increasing radiation in a corrosive environment, in which the component includes an alloy, which in a first, high temperature, has a BCC structure and in a second, lower temperature , has an HCP structure, in which the alloy includes at least one alloy element that has low solubility in the HCP structure and in which the alloy cools rapidly from the first temperature to the second temperature while the phase particles Secondary, which includes said alloy element and which contribute to improving the corrosion properties of the alloy, are separated in the HCP structure, in which the rapid cooling is carried out in two stages, characterized in that the first stage consists of rapid cooling with a relatively lower intensity and the second subsequent stage consists of rapid cooling with an intensity relatively higher ad.
