摘要

报道了在轻水反应堆正常运行条件下，FeCrAl合金的氧化行为。在一项比较研究中，zr基和FeCrAl合金样品在360°C的加压水中被腐蚀长达500天，或在1200°C的蒸汽环境中被氧化3000秒。与zr基合金相比，经过两次试验后，FeCrAl合金的重量变化非常小。采用各种分析方法对feral合金表面氧化物的微观组织进行了表征。结果表明:α-Fe2O3和α-Al2O3的氧化相主要形成于不同的氧化相。

A study of the oxidation of FeCrAl alloy in pressurized water and high-temperature steam environment

The oxidation behaviour of the FeCrAl alloy under normal operating conditions of a light water reactor is reported. In a comparative study, Zr-based and FeCrAl alloy samples were corroded in pressurized 360 °C water for up to 500 days or oxidized at 1200 °C for 3000 s in a steam environment. Compared to Zr-based alloys, the FeCrAl alloy showed extremely low weight change after both tests. The microstructure of the oxides formed on FeCrAl alloys was characterized by various analysing techniques. It was concluded that depending on the test conditions, mostly different oxide phases of α-Fe₂O₃ and α-Al₂O₃ were formed.
