“…V-notches with the radius 0.11 mm, 60° angle, and 0.25 mm depth were machined in the middle of specimens gauge(ASTM E292-01 standard) ( Figure 2b). The stress concentration factor, i.e., the ratio of maximum and nominal stresses, was estimated to be 2.2 at the tip of the notch [12]. In order to remove natural oxides from the surface of the steel and to induce wetting, notched specimens were treated with a chemical flux (chemical composition given in Table 3).…”

Abstract:In this work, the conditions for the occurrence of Liquid Metal Embrittlement (LME) in the ferritic-martensitic steel T91 in contact with lead, Pb, were examined. Slow tensile tests with notched specimens revealed that in a temperature range close to the melting point of Pb, the steel is sensitive to LME (350-400 • C) and to Solid Metal Induced Embrittlement (SMIE) (300 • C). The cracking was stimulated by wetting (using a chemical flux) and the notch effect. It was found that the multi axial stresses state and the high level of plastic strain in front of the notch were the key factors triggering crack initiation.
