Abstract

Corrosion and low-cycle fatigue (LCF) tests were performed on AISI 316L steel specimens in a flowing lithium lead environment. The LCF and corrosion tests were conducted simultaneously in the "LIFUS 2" forced convection loop, at a temperature of 723 K and a flow velocity of approximately 0.01 m/s. The LCF tests, which had a strain amplitude ranging from 0.008 to 0.016, were compared with reference tests performed in an inert argon atmosphere. The results show that liquid Pb17Li has no detrimental effect on the LCF behaviour of 316L at the test temperature of 723 K. The corrosion tests extended from 650 to 1600 h with intermediate steps. Metallographic and SEM-EDAX analyses indicated the presence of an irregular porous ferritic later. The results are discussed in terms of ferrite growth rate and the effect of corrosion phenomena on LCF behaviour. © 1994.
