摘要

本文描述了T91铁素体-马氏体钢在液态共晶PbBi中长期暴露后的行为。根据ISO标准7539-2对钢的小试样进行预加载，随后暴露于PbBi。实验在350°C的流动和静态液态金属介质中进行。实验时间选择为1000小时的流动环境和2000小时的静态环境。暴露后，使用SEM和EDX对试样进行分析。比较和讨论了不同实验条件下试样的表面变化。在监测的博览会中没有观察到裂纹的萌生。

Analysis of resistance of T91 steel under load in liquid PbBi

Abstract This paper describes behaviour of the ferritic-martensitic steel T91 after long-term exposure in liquid eutectic PbBi. Small specimens of the steel were pre-loaded according to the ISO Standard No. 7539-2 and subsequently exposed to PbBi. The experiment was carried out in a flowing and static liquid metal medium at 350°C. The experimental time was selected for the flowing environment at 1000 hours and for static environment at 2000 hours. After exposure, the specimens were analysed by use SEM and EDX. Surface changes of the specimens from different experimental conditions were compared and discussed. The initiation of the cracks wasn´t observed in the monitored expositions.
