“…Changes in the surface state of the sample after chemical etching with BB followed by electrochemical oxidation in the 0.1 M Na 2 SO 4 aqueous solution are depicted in Figure 3b,c. As seen in Figure 3c, anodic oxidation of the amorphous Fe70Cr15B15 alloy (preliminarily treated with BB) in an aqueous solution results only in deep pitting of the surface, as was observed for glassy Fe-40Ni-14P-6B alloy [36].…”

The impact of preliminary treatment (mechanical abrasion; chemical etching and anodization in ionic liquid) on the surface structure and corrosion behavior of Fe70Cr15B15 metal glass was studied. The detachment of the anodic oxide film from untreated Fe-amorphous alloy under anodization in ionic liquid was observed for the first time. The formation of hexagonal nanostructures (cells) on the surface of the Fe70Cr15B15 alloy after mechanical abrasion and following anodization in 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim][BF4]) ionic liquid was also detected for the first time. Electrochemical corrosion of the initial and pretreated amorphous alloy was tested in a Na2SO4 aqueous solution. The resistance to corrosion was found to be enhanced slightly after mechanical abrasion. The sample with hexagonal nanostructures obtained after anodization of the mechanically abraded sample demonstrated a more significant anodic shift in the corrosion potential (Ecorr = + 379 mV) compared with that for the initial alloy (Ecorr = −125 mV).

“…Problems as diverse as corrosion-assisted cracking [1,2] and high velocity impact or dynamic crack propagation [3][4][5] are characterized by the appearance of branched cracks. In this paper, we present extensions of the generalized finite element method (GFEM) presented in [6] that are able to handle through-thethickness three-dimensional branched discontinuities which are independent of the finite element (FE) mesh.…”

SUMMARYThis paper presents high-order implementations of a generalized finite element method for throughthe-thickness three-dimensional branched cracks. This approach can accurately represent discontinuities such as triple joints in polycrystalline materials and branched cracks, independently of the background finite element mesh. Representative problems are investigated to illustrate the accuracy of the method in combination with various discretizations and refinement strategies. The combination of local refinement at crack fronts and high-order continuous and discontinuous enrichments proves to be an excellent combination which can deliver convergence rates close to that of problems with smooth solutions.
