Abstract

Iron-Chromium-Aluminum (FeCrAl) alloys are candidate materials for the cladding of light water reactor (LWR) fuels. The FeCrAl alloys in general range in Cr composition from 12% (C26M) to 21% (APMT). In this work, the general corrosion behavior of Additively Manufactured (AM) C26M coupons was compared to the behavior of traditional Powder Metallurgy (PM) coupons. Immersion testing were conducted for 12 months at 288 °C and 330 °C in pure water containing either oxygen or hydrogen. Results show that the mass change of AM specimens in hydrogenated water was like the mass change of PM specimens. In oxygenated water, the mass change of AM coupons was higher and less reproducible than for the PM coupons. Porosity in the AM specimens makes their behavior less predictable in high-temperature water.

堆外轻水反应堆环境中添加剂制造的铁铬铝的腐蚀行为

铁-铬-铝（FeCrAl）合金是轻水反应堆（LWR）燃料包壳的候选材料。一般来说，铁铬铝合金的铬含量从 12% (C26M) 到 21% (APMT)不等。在这项工作中，将快速成型（AM）C26M 试样的一般腐蚀行为与传统粉末冶金（PM）试样的行为进行了比较。在含氧或含氢的纯水中，分别在 288 °C 和 330 °C 温度下进行了为期 12 个月的浸泡测试。结果表明，AM 试样在氢化水中的质量变化与 PM 试样的质量变化相同。在含氧水中，AM 试样的质量变化比 PM 试样大，且重复性较差。AM 试样中的多孔性使其在高温水中的行为更难预测。

期刊介绍： npj Materials Degradation considers basic and applied research that explores all aspects of the degradation of metallic and non-metallic materials. The journal broadly defines ‘materials degradation’ as a reduction in the ability of a material to perform its task in-service as a result of environmental exposure. The journal covers a broad range of topics including but not limited to: -Degradation of metals, glasses, minerals, polymers, ceramics, cements and composites in natural and engineered environments, as a result of various stimuli -Computational and experimental studies of degradation mechanisms and kinetics -Characterization of degradation by traditional and emerging techniques -New approaches and technologies for enhancing resistance to degradation -Inspection and monitoring techniques for materials in-service, such as sensing technologies
