Stabilized nanograin boundaries in nickel-molybdenum alloys result increased hardness with decreasing grain size.
Recent studies indicate that eutectic high-entropy alloys can simultaneously possess high strength and ductility, which have potential applications in industrial fields. Nevertheless, microstructural origins of the excellent strength–ductility combination remain unclear. In this study, an AlCoCrFeNi2.1 alloy was prepared with face-centered cubic (FCC)(L12)/body-centered-cubic (BCC)(B2) modulated lamellar structures a remarkable ultimate tensile (1351 MPa) ductility (15.4%) using classical...
Abstract Precipitation-hardening high-entropy alloys (PH-HEAs) with good strength−ductility balances are a promising candidate for advanced structural applications. However, current HEAs emphasize near-equiatomic initial compositions, which limit the increase of intermetallic precipitates that closely related to alloy strength. Here we present strategy design ultrastrong high-content nanoprecipitates by phase separation, can generate matrix in situ while forming strengthening phases,...
High‐throughput explorations of novel thermoelectric materials based on the Materials Genome Initiative paradigm only focus digging into structure‐property space using nonglobal indicators to design with tunable electrical and thermal transport properties. As genomic units, following biogene tradition, such include localized crystal structural blocks in real or band degeneracy at certain points reciprocal space. However, this approach does not consider how differentiate from others. Here,...
Body-centred cubic magnesium-lithium-aluminium-base alloys are the lightest of all structural alloys, with recently developed alloy compositions showing a unique multi-dimensional property profile. By hitherto unrecognised mechanisms, such also exhibit exceptional immediate strengthening after solution treatment and water quenching, but strength eventually decreases during prolonged low temperature ageing. We show that phenomena due to precipitation semi-coherent D03-Mg3Al nanoparticles...
Abstract Additive manufacturing (AM) creates digitally designed parts by successive addition of material. However, owing to intrinsic thermal cycling, metallic produced AM almost inevitably suffer from spatially dependent heterogeneities in phases and mechanical properties, which may cause unpredictable service failures. Here, we demonstrate a synergistic alloy design approach overcome this issue titanium alloys manufactured laser powder bed fusion. The key our is in-situ alloying Ti−6Al−4V...
High strength aluminum alloys are widely used but their is reduced as nano-precipitates coarsen rapidly in medium and high temperatures, which greatly limits application. Single solute segregation layers at precipitate/matrix interfaces not satisfactory stabilizing precipitates. Here we obtain multiple interface structures an Al-Cu-Mg-Ag-Si-Sc alloy including Sc layers, C L phases well a newly discovered χ-AgMg phase, partially cover the θ' By atomic resolution characterizations ab initio...
Thin-film composite reverse osmosis membranes have remained the gold standard technology for desalination and water purification nearly half a century. Polyamide films offer excellent permeability salt rejection but also suffer from poor chlorine resistance, high fouling propensity, low boron rejection. We addressed these issues by molecularly designing polyester thin-film membrane using co-solvent-assisted interfacial polymerization to react 3,5-dihydroxy-4-methylbenzoic acid with trimesoyl...
