As observed in the design of antenna reflectors and rocket bodies, both flat and 3Dshaped honeycomb cores are used in the field of aerospace engineering. This study illustrates a new strategy to fabricate arbitrary cross-section honeycombs with applications of advanced composite materials by using the concept of the kirigami honeycomb, which is made from single flat sheets and has periodical sl...

An NbC-Fe composite powder was synthesized from an Nb₂O₅/Fe/C mixture by electrochemical reduction and subsequent carbonization in molten CaCl₂-NaCl. The composite has a core-shell structure, in which NbC acts as the cores distributing in the Fe matrix. A strong bonding between NbC and Fe is benefit from the core-shell structure. The sintering and electrochemical reduction processes were invest...

Initial powder mixtures of Cu, Fe and Co are exposed to severe plastic deformation by high-pressure torsion prepare solid solutions. A broad range compositions is investigated, whereas this study aims at the synthesis soft magnetic materials therefore formation a homogeneous nanocrystalline microstructure. For intermediate ferromagnetic contents, room temperature yields single-phase supersatura...
