WebJun 1, 2005 · Abstract. Previous studies on T91 steel in its standard metallurgical state do not provide evidence for liquid metal embrittlement by eutectic Pb–Bi. In this paper, we show that this steel can be embrittled by Pb–Bi when direct contact between the steel and the liquid metal is obtained by prior ion beam sputtering of the native oxidized film. WebThe susceptibility of the ferritic–martensitic steels T91 and EUROFER97 to liquid metal embrittlement (LME) in lead alloys has been examined under various conditions. T91, which is currently the most promising candidate material for the high temperature components of the future accelerator driven system (ADS) was tested in liquid lead …
