Abstract

The corrosion fatigue damage mechanism of T91 steel in liquid lead-bismuth eutectic (LBE) at 150–550 °C was investigated. The results showed that the corrosion behavior is dependent on temperature. The properties of the oxide scale may affect the fatigue crack initiation and embrittlement susceptibility. The crack propagated along the prior or deformed sub- grain boundaries (GBs) at 150 °C and 350 °C, which was characterized by quasi-cleavage cracking. The intergranular oxidation and Pb/Bi permeation into the deformed GBs significantly degraded the fatigue properties at 550 °C. The temperature dependence of fatigue damage mechanism was discussed.
