Abstract：

Liquid　metal　embrittlement　(LME)　of　an　Fe10Cr4Al　(wt%)　ferritic　alloy　was　tested　in　lead-bismuth　eutectic　(LBE)　at　350　degrees　C　using　slow　strain　rate　tensile　tests.　The　results　show　that　this　alloy　is　highly　susceptible　to　LME.　The　strong　LME　effect　is　manifested　by　a　substantial　reduction　in　ductility　and　completely　cleaved　fracture　surfaces.　Transgranular　cleavage　and　intergranular　cracking　are　the　major　fracture　modes.　The　LME　susceptibility　is　slightly　weaker　in　oxygen-saturated　LBE　than　oxygen-depleted　LBE　due　to　the　presence　of　a　double-layer　scale　consisting　of　magnetite　and　Al-rich　spinal.　The　oxide　scale　is　fragmented,　indicative　of　a　brittle　nature.
