The synergistic action and interplay of hydrogen embrittlement mechanisms in steels and iron: Localized plasticity and decohesion
TL;DR: In this paper, a review of the synergistic interplay of hydrogen embrittlement mechanisms in STEEL and IR is presented, with a particular emphasis on the proposal of the novel and unified HELP+HEDE model based on the specific microstructural mapping of the dominant HE mechanisms with implications on the fracture process and resulting hydrogen-assisted fracture modes.

Effects of hydrogen on the properties of iron and steel
TL;DR: In this paper, the effects of hydrogen on the physical and mechanical properties of iron and steel are reviewed and a new mechanism for the cold work peak for hydrogen in iron is considered.

Hydrogen-enhanced localized plasticity—a mechanism for hydrogen-related fracture
TL;DR: In this article, a theory of hydrogen shielding of the interaction of dislocations with elastic stress centres is outlined, which can account for the observed hydrogen-enhanced dislocation mobility.

Kinetics of strain-induced martensitic nucleation
Gregory B. Olson,Morris Cohen +1 more
TL;DR: In this paper, an expression for the volume fraction of martensite vs plastic strain is derived by considering the course of shear-band formation, the probability of shears-band intersections, and probability of an intersection generating a martensitic embryo.

Dislocation and twin substructure evolution during strain hardening of an Fe-22 wt.% Mn-0.6 wt.% C TWIP steel observed by electron channeling contrast imaging
TL;DR: In this article, the authors studied the kinetics of the substructure evolution and its correspondence to the strain hardening evolution of an Fe-22 wt.% Mn-0.6 wt% C TWIP steel during tensile deformation by means of electron channeling contrast imaging (ECCI) combined with electron backscatter diffraction (EBSD).
