Crack initiation due to liquid metal embrittlement for the steel T91 and two ODS steels in Liquid lead
Original language description
Ferritic-martensitic steels and oxide dispersion strengthened steels are materials intensively studied because of their potential to be used for construction of Gen IV fast nuclear reactors. Steels were developed for fast breeder reactors (high-temperature strength and swelling resistance under irradiation). In this study the effect of liquid lead on the crack growth rate of the steels was evaluated. Steels T91, MA957, PM2000 were used to evaluate their interaction with liquid lead under stress corresponding to maximum requested design condition. Liquid Metal Embrittlement (LME) initiation tests were conducted on pre-loaded specimens in flowing liquid metal loops. The experiments were carried out at 400°C and post-test evaluation was performed. Some specimens were pre-treated with a chemical flux, to induce wetting of Pb on the steel some were polished or ground. Liquid Metal Embrittlement was not observed on the surface of any of the pre-loaded specimens after the exposure in liquid lead at 400°C for 500 hours. The results are discussed and compared with previous accelerated tests.
