TL;DR: In this paper, it was shown that the cathodic reaction is not restricted to the flanks of the crack or to the crack mouth, but occurs predominantly on the external surfaces, as postulated in the coupled environment fracture model.

TL;DR: In this article, the authors used modified wedge-opening-loading (WOL) specimens to investigate the susceptibility of bainite/martensite dual-phase high strength steel to hydrogen embrittlement.
Abstract: It is very imperative to improve delayed fracture properties of high strength steel, which may enlarge its usage. The published literature shows that the susceptibility to hydrogen embrittlement of a novel 1 500 MPa bainite/martensite dual-phase high strength steel is inferior to that of conventional quench-tempered high strength steel. The stress corrosion cracking (SCC) in a 3.5% NaCl solution for novel 1 500 MPa bainite/ martensite dual-phase high strength steel was investigated in this paper by using modified wedge-opening-loading (WOL) specimens. The experimental results show that KISCC for novel 1 500 MPa bainite/martensite dual-phase high strength steel is larger than 50 MPa·m1/2, exceeding conventional high strength steel. Its crack growth rate (da/dt)II is about 1×10−5 mm/s, which is less than that of conventional high strength steel. Hydrogen trapping phenomena in the steel were investigated by electrochemical permeation technique. The lath boundaries and stable retained austenite are beneficial hydrogen trap, slowing down the segregation of hydrogen on the crack tip, hence KISCC increases and crack growth rate decreases.

TL;DR: In this paper, a zero-resistance ammeter was used to monitor the coupling current that flows from the crack in an insulated compact tension (CT) specimen to external cathodes.

TL;DR: In this paper, a nanoindenter/atomic force microscope was used to drive controlled grain boundary crack growth under load in an active solution, and electron microscopy examination confirmed the growth of the crack along the grain boundary.
