TL;DR: In this paper, the microstructure, local mechanical properties and local stress corrosion cracking susceptibility of an SA508-52M-316LN domestic dissimilar metal welded safe-end joint used for AP1000 nuclear power plant prepared by automatic gas tungsten arc welding was studied by optical microscopy, scanning electron microscopy and an energy dispersive X-ray spectroscopy system.

TL;DR: In this article, the authors systematically evaluated the stress corrosion cracking behavior of 316L heat affected zones (HAZ) in 316L stainless steel/Inconel 52M dissimilar metal welded joint (DMWJ) in simulated primary water.

TL;DR: In this paper, the surface state has no influence on the phase composition of the oxide films but obviously affects the thickness of oxide films and the morphology of the oxides (number & size).

TL;DR: In this paper, the authors measured the stress corrosion cracking (SCC) at the fusion boundary (FB) for 316L/52M weld joints using direct current potential drop systems in borated and lithiated high temperature water.

TL;DR: In this paper, the crack growth rates of two duplicate compact tension (CT) specimens were measured using direct current potential drop method and the effects of stress intensity factor (K, changes from 21 to 41 MPa√m), dissolved oxygen (DO), changes from <10 to 2000 ppb, and dissolved hydrogen (DH, 2800 ppb) on CGRs were comprehensively examined.
