Abstract Grain boundaries (GBs) are dominant imperfections in nanocrystalline materials that form a complex 3D network. Solute segregation to GBs is strongly coupled the GB character, which governs stability and macroscopic properties of nanostructured materials. Here, transmission electron microscopy atom probe tomography (APT) correlation framework developed retrieve character composition at highest spatial resolution chemical sensitivity by correlating 4D scanning precession diffraction...
Transition metal-based intermetallic materials are candidates for high-temperature structural applications. However, they limited by their low fracture toughness at ambient temperature. Given Fe is a low-cost metal with environmental impact, it necessary to design tough Fe-based alloys. We report novel ferrite-Fe2Mo synthesized through arc melting and quenching of Fe0.78Mo0.22 alloy. Diffusional-displacive mixed-mode transformation the parent ferrite phase resulted in formation nanocomposite...
Transition metal-based intermetallic materials are candidates for high-temperature structural applications. However, they limited by their low fracture toughness at ambient temperature. Given Fe is a low-cost metal with environmental impact, it necessary to design tough Fe-based alloys. We report novel ferrite-Fe2Mo composite high hardness (HV2) of 7.54 GPa and exceptional (evidenced resistance indentation cracking). It was achieved diffusional-displacive mixed-mode transformation the parent...
