摘要: Abstract Two ferritic/martensitic steels, T91 steel and newly developed SIMP steel, were subject to tensile test after being oxidized in the liquid lead-bismuth eutectic (LBE) at 873 K for 500 h, 1000 h 2000 h. Tensile tests also carried out on steels only thermally aged 873 K. The result shows that thermal aging has no effect. Exposure LBE leads a slight decrease strength, but large elongation when tested When 2000 h exposure, strength of decreases slightly, from 39% 21%. For SIMP, are slightly 44% 28%, elongation, respectively. room temperature larger percentage reductions changes little.
