Abstract

Zirconium is used as a structural material for use in aggressive environments, including the core of nuclear reactors. The traditional technology of manufacturing the structural elements of zirconium nuclear reactors is characterized by a long technological process and a significant amount of waste in the form of metal shavings. The paper presents the results of an alternative technology, spark plasma sintering, for manufacturing zirconium products. A complex of microstructural and mechanical studies of the obtained samples was carried out according to the ASTMB-351 standard. The sintering of zirconium powder and options for subsequent processing by various methods, including non-standard ones such as radial shear rolling, are justified.

摘要

锆被用作在包括核反应堆堆芯在内的侵蚀性环境中使用的结构材料。制造锆核反应堆结构元件的传统技术具有工艺流程长和大量金属屑形式的废料的特点。本文介绍了一种用于制造锆产品的替代技术——放电等离子烧结的结果。根据ASTMB - 351标准对所得样品进行了微观结构和力学研究的综合分析。对锆粉的烧结以及包括径向剪切轧制等非标准方法在内的各种后续加工选项进行了论证。
