Heterostructured materials are an emerging class of with superior performances that unattainable by their conventional homogeneous counterparts. They consist heterogeneous zones dramatic (>100%) variations in mechanical and/or physical properties. The interaction these hetero-zones produces a synergistic effect where the integrated property exceeds prediction rule-of-mixtures. heterostructured field explores heterostructures to control defect distributions, long-range internal stresses, and...
Abstract This study addresses the challenge of designing simple and environmentally friendly methods for preparation effective electromagnetic wave (EMW) absorbing materials with tailored microstructures multi‐component regulation. N, O doped walnut‐like porous carbon composite microspheres loaded FeCo nanoparticles (WPCM/Fe–Co) are synthesized through high‐temperature carbonization combined soap‐free emulsion polymerization hydrothermal methods, avoiding use toxic solvents complex...
A key challenge in synthesizing anisotropic nanocomposite magnets is to form crystallographic texture for R2Fe14B crystals R-lean alloys (R=rare earth, R<10 at. %). Here, we demonstrate a (00l) development Nd2Fe14B nanocrystals Nd-lean amorphous Nd9Fe85B6 under hot deformation at large uniaxial stress of ∼310 MPa. The unusual formation attributed preferential nucleation matrix the stress. present study provides an opportunity yield from and thus wide interest.
Heterostructures with large microstructural heterogeneities have been introduced in structural materials for superior strength-ductility combinations, but their effects on functional properties remain little explored. Here I highlight the enormous potential of heterostructures to resolve conflicting materials. The challenges, strategies and prospects heterostructured are discussed. Rational design will open up new opportunities creating unprecedented performance or functionalities. This...
In general, there is a trade-off between magnetization and coercivity in nanocomposite magnets. Here, we demonstrate simultaneous enhancement of both the bulk α-Fe/Nd2Fe14B magnets prepared via severe plastic deformation (SPD) compared with thermally annealed The enhanced results from high fraction (>30%) α-Fe phase induced by SPD, while increase 4.6 to 7.2 kOe attributed an domain wall pinning strength. This study shows energy product possible for large inclusion soft-magnetic phase.
Materials with multifunctionality affect society enormously. However, the inability to surmount multiple functionality trade-offs limits discovery of next-generation multifunctional materials. Departing from conventional alloying design philosophy, we present a hierarchical nanostructure (HNS) strategy simultaneously break performance in material. Using praseodymium-cobalt (PrCo 5 ) ferromagnet as proof concept, resulting HNS outperforms contemporary high-temperature ferromagnets 50 138%...
The unprecedented hardness of nt-diamond originates from high lattice frictional stress and athermal stress.
The control of nanocrystal formation in amorphous alloys is particular importance for the development advanced nanocrystalline materials. In present study, authors succeeded controlling α-Fe and Nd2Fe14B nanocrystallization processes Nd9Fe85B6 by a combination severe plastic deformation at room temperature subsequent thermal annealing. α-Fe∕Nd2Fe14B nanocomposite magnets prepared this approach possess homogeneously distributed nanocrystals with small size, 15nm phase 26nm Nd2Fe14B, therefore...
Permanent-magnet materials are critical components for green energy technologies, but the intrinsic trade-off between saturation magnetization and coercivity limits their achievable density. Here, a new concept of ordered structures is proposed to develop high-performance permanent magnets. This strategy enables rare combination high by introducing reversal mechanisms associated with structures. Implications challenges building strong magnets discussed. Perspective aims draw attention...
Fabricating high-performance solar steam evaporators using 3D porous substances with natural advantages in light absorption, water transmission and thermal insulation has gradually become a research hotspot.
Abstract The hardness of nanotwinned diamond (nt-diamond) is reported to be more than twice that the natural diamond, thanks fine spaces between twin boundaries (TBs), which block dislocation propagation during deformation. In this work, we explore effects additional TBs in nt-diamond using molecular dynamics (MD) calculations and introduce a novel intersectional (int-diamond) template for future laboratory synthesis. int-diamond predicted by first analyzing individual slip modes twinned...
