Character of Liquid Metal Embrittlement of the Steel T91 in Contact with Lead Bismuth Eutectic

Popis výsledku v původním jazyce

Presentation at Rome, Final MATTER International WorkShop, Italy, October 20-22 th, 2014. This work summarizes results of the work carried out in CVR on the evaluation of the susceptibility to LME for the steel T91 in contact with LBE at 300-350°C. The work, carried out in the past few years, through tensile and fracture toughness tests, revealed a marked sensitivity to embrittlement for the T91 in contact with LBE. Here, the fracture resistance test results are given which were gathered during well defined conditions and according ASTM standard. It was found that LBE decreases JIC by more than 30% of the air value. The results are discussed based on the observations of the fracture surface evidencing LME occurrence. The fracture toughness measured inLBE is proposed to be the appropriate value for fracture resistance evaluation applied to extension of a pre-existed LME crack.
