Uniaxial　creep-to-rupture　tests　at　550　and　600　degrees　C　under　a　constant　load　of　300　MPa　have　been　performed　to　study　the　effect　of　lead-bismuth　eutectic　(LBE)　on　the　creep　failure　behavior　of　a　solution-annealed　15-15Ti　steel.　The　results　show　that　the　secondary　creep　rate　of　the　steel　tested　in　LBE　at　550　and　600　degrees　C　is　56　and　6　times　higher　than　that　tested　in　air　at　the　same　temperatures,　respectively.　The　transition　time　from　the　primary　creep　to　the　secondary　creep　is　largely　shortened　by　LBE.　As　a　consequence,　the　creep　life　of　15-15Ti　in　contact　with　LBE　is　reduced　remarkably.　The　severe　degradation　of　the　creep　performance　is　attributed　to　uniform　dissolution　corrosion　(elemental　leaching)　and　especially　localized　intergranular　cracking.
