Palladium Membrane with High Density of Large-Angle Grain Boundaries to Promote Hydrogen Diffusivity
Membranes, 2022 A higher density of large-angle grain boundaries in palladium membranes promotes hydrogen diffusion whereas small-angle grain boundaries suppress it. In this paper, the microstructure formation in 10 µm thick palladium membranes is tuned to achieve a ...

Effect of serrated grain boundary on stress corrosion cracking of Alloy 600
Nuclear Engineering and Technology, 2018 The effect of a serrated grain boundary on stress corrosion cracking (SCC) of Alloy 600 was investigated in terms of improvement of SCC resistance. Serrated grain boundaries and straight grain boundaries were obtained by controlled heat treatment.

Grain boundary dislocations in plane matching grain boundaries [PDF]
Physica Status Solidi (a), 1979 Plane matching (PM) boundaries are defined as boundaries in which a single stack of planes of indices (hkl) in each crystal adjoining the boundary is either parallel, or nearly parallel, and where no other significant lattice matching exists. A search was made (by transmission electron microscopy) for possible intrinsic secondary grain boundary ...

An understanding of hydrogen embrittlement in nickel grain boundaries from first principles
Materials & Design, 2021 Here, the segregation and accumulation of hydrogen in Ni grain boundaries, and its effects on cohesion and tensile mechanical strength were studied by means of density functional theory simulations. Three model grain boundaries were considered: the Σ3(11¯
