Abstract：

Liquid　metal　embrittlement　(LME)　susceptibility　of　three　FeCrAl　alloys　(i.e.,　Fe10Cr4Al,　Fe15Cr4Al　and　Fe10Cr6Al,　wt%)　was　tested　in　oxygen-saturated　and　-depleted　liquid　lead-bismuth　eutectic　(LBE)　at　350　?C　using　slow　strain　rate　tensile　tests.　The　results　show　that　all　three　alloys　are　very　susceptible　to　LME,　manifested　by　a　severe　reduction　in　total　elongation　to　failure　and　prevailing　cleavage　on　fracture　surfaces.　LME　is　delayed　in　oxygen-saturated　LBE,　due　to　a　dewetting　effect　of　surface　oxides.　In　three　alloys,　Fe10Cr6Al　is　most　susceptible　to　LME,　especially　in　presence　of　oxygen-depleted　LBE.
