The enhancement of near-field radiative heat transfer (NFRHT) has now become one of the research hotspots in the fields of thermal management and imaging due to its ability to improve the performance of near-field thermoelectric devices and near-field imaging systems. In this paper, we design three structures (multilayer structure, nanoporous structure, and nanorod structure) based on high-entropy alloys to realize the enhancement of NFRHT. By combining stochastic electrodynamics and Maxwell-Garnett's description of the effective medium, we calculate the radiative heat transfer under different parameters and find that the nanoporous structure has the largest enhancement effect on NFRHT. The near-field heat transfer factor (q) of this structure (q = 1.40×109 W/ (m2•K)) is three times higher than that of the plane structure (q = 4.6×108 W/ (m2•K)), and about two orders of magnitude higher than that of the SiO2 plate. This result provides a fresh idea for the enhancement of NFRHT and will promote the application of high-entropy alloy materials in near-field heat radiation.

High saturation magnetization and low coercivity are required for soft magnetic materials. This study investigated the Co47.5Fe28.5Ni19Si3.3Al1.7 high-entropy soft magnetic skeleton was prepared by selective laser melting. Then Al was pressure infiltrated into skeletons to obtain a dense composite material. The high-entropy composite materials possessed favorable compressive ductility and moderate soft magnetic properties. The high-entropy composite materials were obtained with Ms being 97.1 emu/g, 79.8 emu/g, 33 emu/g and possessing 19 Oe, 15.8Oe and 17Oe of Hc, respectively. However, the magnetostriction coefficient remains low level, about 5ppm. These reported properties are attributed to the special structure of the material studied in present experiment. Nevertheless, a novel strategy of structural designing was proposed in this paper.

Undercooling of ternary CoCrNi medium entropy alloy (MEA) was achieved by molten glass fluxing method. The influence of undercooling on microstructure and mechanical properties of was investigated. The microstructure changes during the undercooling process identified by transmission electron microscope and scanning electron microscope shows that the grain size and intergranular phase all change after the undercooling treatment. The yield strength of the ternary MEA increased significantly after undercooling treatment, which attribute to the refined grain size and the formation of the new phase. Undercooling method can be used as a potential method to modify the microstructure and improve the mechanical properties of MEAs.

The present work investigates the effect of Ni on the microstructure, mechanical properties, and corrosion resistance of CoCrFeNixAl0.15Ti0.1 high-entropy alloys. It was found that the appropriate addition of Ni element in the alloy is beneficial to reduce the average grain size of the alloy. The yield strength and tensile strength of the alloy under fine-grain strengthening have also been increased, while the ductility of the system in this study has not been significantly affected. In terms of corrosion resistance, CoCrFeNixAl0.15Ti0.1 high-entropy alloys form a dense passive film at open circuit potential, possessing good corrosion resistance. However, with the excessive addition of Ni content in the alloy, the pitting corrosion resistance of the alloy in the environment of chloride ions will decrease due to the relative decrease of the relative content of Cr element. This work also can provide guidances for the design and development of new precipitation-strengthened CoCrFeNi-based high-entropy alloys with excellent comprehensive properties.

This work aims to explore WC-G201 high entropy cemented carbides properties fabricated by spark plasma sintering with AlCoCrFeNiTi0.2 and WC as binder phase and hard phase respectively. AlCoCrFeNiTi0.2 powder and WC powder were mixed at the mass ratio of 5: 95, 10: 90 and 15: 85 respectively, and then via SPS at 1300℃ for 5min. The results show that the binder phase has good wettability to WC, and with the increase of binder phase content, the hardness of the alloy decreases gradually, fracture toughness increases first and then decreases, the maximum value is 7.88 MPa m1/2. It is estimated that the comprehensive mechanical property of cemented carbides is the best when the binder content is between 5wt% and 10wt%.

AZ91D magnesium alloy rolled under four rolling conditions, namely cold rolling, electric pulse cold rolling, hot rolling and electric pulse hot rolling, and the first principles calculation of Mg with or without external electric field carried out. The results show that: The application of pulse current in the rolling process of AZ91D magnesium alloy can effectively improve the edge crack of the sample, optimize the texture of AZ91D magnesium alloy and reduce its texture strength, promote the generation of tensile twins and the transition from small Angle grain boundaries to large Angle grain boundaries, and thus improve the plastic forming ability of AZ91D magnesium alloy. Make it more prone to plastic deformation. Compared with ordinary rolling, the microhardness of α-Mg matrix decreases by 15%. The tensile strength and elongation increased from 137MPa and 3.4% to 169MPa and 4.7%, respectively. The results show that the stiffness of Mg decreases and the Poisson's ratio of Mg increases when the electric field applies. When the B/G value is greater than 1.75, the plasticity of Mg is improved. The fault energy at the base surface of Mg does not change much, while the fault energy at the prismatic surface of Mg decreases obviously, showing the external electric field mainly affects the prismatic surface slip of Mg, which makes the prismatic surface slip easier to start, and thus improves the plastic forming ability of Mg.

In summary, a novel structure of MOF based on 1,4–di ([2,2':6',2''terpyridin] -4'-yl)benzene and 1,4-naphthalenedicarboxylic acid has been constructed through hydrothermal reaction. The Ni-MOF displays one dimensional zigzag chain, which connect each other by hydrogen bonding to form three dimensional supramolecule with large channels. The conjugated systems of the terpyridin and benzene ligands enhance the chain rigidity, accelerate the electron transport. The massive channels provides electrolyte rapid transfer. By the structural feature aforementioned, the Ni-MOF demonstrates stable electrochemical performance as suprocapacitor.

The problems of traditional concrete such as brittleness, poor toughness and short service life of concrete engineering under acid rain or marine environment need to be solved urgently. Hydrated calcium silicate (C-S-H) is a key component to improve the mechanical properties and durability of concrete. However, the traditional method of concrete material design based on empirical models or comparative tests has become a bottleneck restricting the sustainable development of concrete. The synthesis method, molecular structure and properties of C-S-H were systematically described in this paper; The interface structure and interaction of graphene oxide / calcium silicate hydrate (C-S-H / GO) were discussed. On this basis, the saturated and unsaturated transport characteristics of ions and water molecules in C-S-H / GO nanochannels under the environment of ocean and acid rain were introduced. The contents of this review provide the basis for improving the multi-scale transmission theory and microstructure design of concrete. It has important guiding significance for analyzing and improving the service life of concrete in complex environment.
