grain boundary depletion and migration during selective oxidation of cr in a ni 5cr binary alloy exposed to high temperature hydrogenated water
Scripta Materialia, 2014Co-Authors: Daniel K Schreiber, Matthew J Olszta, Stephen M BruemmerAbstract:High-resolution microscopy of a high-purity Ni–5Cr alloy exposed to 360 °C hydrogenated water reveals intergranular selective oxidation of Cr accompanied by local Cr depletion and diffusion-induced grain boundary migration (DIGM). The corrosion-product oxide consists of a porous, Interconnected Network of Cr2O3 platelets, with no further O ingress into the metal ahead. Extensive grain boundary depletion of Cr (to

Scripta Materialia, 2014Co-Authors: Daniel K Schreiber, Matthew J Olszta, Stephen M BruemmerAbstract:High-resolution microscopy of a high-purity Ni–5Cr alloy exposed to 360 °C hydrogenated water reveals intergranular selective oxidation of Cr accompanied by local Cr depletion and diffusion-induced grain boundary migration (DIGM). The corrosion-product oxide consists of a porous, Interconnected Network of Cr2O3 platelets, with no further O ingress into the metal ahead. Extensive grain boundary depletion of Cr (to <0.05 at.%), typically 20–100 nm wide, is observed as a result of DIGM, and reaches depths of many micrometers beyond the oxidation front.

zinc subjected to plastic deformation by complex loading and conventional extrusion comparison of the microstructure and mechanical properties
Materials & Design, 2017Co-Authors: K Piela, M Wrobel, K Sztwiertnia, M Jaskowski, J Kawalko, M Bieda, M Kiper, A JarzebskaAbstract:Abstract The microstructure and properties of cast and hot extruded zinc subjected to plastic deformation by conventional extrusion and by extrusion with a forward-backward rotating die (KoBo) were studied. KoBo significantly increased the mechanical properties of both initial materials compared with conventional extrusion. The improvement of the mechanical properties is related to the lower temperature at which the KoBo process can be carried out. Extrusion with a forward-backward rotating die leads to grain refinement and promotes the formation of a composite-like microstructure with a hard matrix, forming an Interconnected Network of boundaries filled with a softer phase. New areas of application for zinc obtained by the KoBo method are opened.

macroscopic 3d porous graphitic carbon nitride monolith for enhanced photocatalytic hydrogen evolution
Advanced Materials, 2015Co-Authors: Qinghua Liang, Zhenghong Huang, Feiyu Kang, Quanhong YangAbstract:A macroscopic 3D porous graphitic carbon nitride (g-CN) monolith is prepared by the one-step thermal polymerization of urea inside the framework of a commercial melamine sponge and exhibits improved photocatalytic water-splitting performance for hydrogen evolution compared to g-CN powder due to the 3D porous Interconnected Network, larger specific surface area, better visible light capture, and superior charge-separation efficiency.
