    The advancement of microwave technology has spurred the development of electromagnetic (EM) protection technology. Being capable of dissipating excess electromagnetic radiation in the form of heat, EM wave absorbing materials have gathered widespread attentions. Confronted with complex EM environment, it is of great significance to explore EM wave absorbing materials with both strong and broadband absorbing capacity within the frequency band of 1 to 18 GHz. At present, the design methods for EM wave absorbing materials mainly include nano-composite construction and doping modification. Through combining dielectric loss-type and magnetic loss-type nanomaterials, the dielectric and magnetic loss coupling can be achieved. However, complex preparation process, difficulty in accurately controlling the dispersion of nanofillers and poor high-temperature stability and resistance to oxidation are the main drawbacks for these types of materials. Ultra-high temperature ceramics (UHTCs) possess good thermal stability and resistance to oxidation, however, the poor impedance match makes it unsuitable for EM wave absorption. Through designing and preparing high-entropy ceramics containing magnetic components, strong and broadband absorbing capability can be achieved in UHTCs. The high-entropy design paradigm can simultaneously adjust the conductivity and enhance the magnetic loss capability, which opens a new window to tune the impedance match for dielectric materials with high conductivity.

    In this paper, the true stress-strain data of Haynes 282 alloy were obtained by conducting isothermal compression tests on a thermal-mechanical simulator.Haynes 282 alloy shows typical dynamic recrystallization characteristic during the deformation process at elevated temperature.Moreover, the flow stress was quite sensitive to the thermodynamic parameters and represents complicated highly-nonlinear relationship with the thermodynamic parameters. In order to accurately describe and predict the true stress-strain relationship of Haynes 282 alloy, a back-propagation neural network was constructed by employing hot deformation parameters as the inputs, and employing flow stress as the output. The evaluation results of the constructed neural network show that the constructed neural network in this research can accurately characterize the hot flow behavior of Haynes 282 alloy. Accurate simulation of the hot flow behavior of Haynes 282 alloy is achieved by implanting the neural network into a finite element software in the form of material subroutine and constructing the finite element model of isothermal compression test.

    The isothermal stamping process of hemisphere shell for the large-size TA7ELI helium cylinder used for future launch vehicles had been researched in this work. The isothermal stamping process of hemisphere shell was simulated by finite element analysis software before a forming process, the influence of the process on the material properties was investigated by comparing the changes of the material microstructure and mechanical properties before and after the forming. Experimental result indicates that during isothermal stamping, the stress and strain of the material gradually extends from the core to the edge, the applied load reaches the maximum value when the forming process operates later period. Furthermore, the thinnest position of the hemisphere shell is around the center of the ball bottom. The grain morphology and size of TA7ELI material changes little after stamping, and the strength of the shell at room temperature and 20 K is almost the same as that before forming. The elongation of the shell at room temperature increases after forming, and the elongation of the bottom of the shell at 20 K decreases but still meets the requirements.

    Micro porosity is the main issue in wire arc additive manufacturing (WAAM) of 2219 aluminum alloy. In this study, the effect of process parameters on the porosity characteristic of WAAM 2219 aluminum alloy was quantitatively investigated. It is found that the porosity was influenced by the heat input. When the heat input is low, the porosity increases with the increasing of heat input due to the nucleating and growing of pores. When the heat input is high, the porosity decreases with the increasing of heat input due to the escaping of pores. The porosity is below 0.2% when the heat input is as low as 230.5 J/mm or as high as 439.5 J/mm.

    Characterizing the axial compressive properties is always the difficulty in the fields of investigating the mechanical performance of the composite materials. In this paper, the pros and cons of four test methods for determining the compressive properties of the composite materials are comparatively summarized, by experimental investigations, mechanism analysis and computational simulations, based on domestic T800-grade composites and M40J-grade composite. Additionally, the optimized test conditions are proposed. The results of experiments and simulations indicate that the compressive strength determined by the test method of GB/T 3856—2005 is decreased by 9% than that of the test method of ASTM D3410—2016, due to premature failure, although the compressive force is both introduced through shear for the two methods. Whereas, the compressive strength measured by the end-loaded method of SACMA SRM 1R-94 is 3% to 6% higher than that of the method of ASTM D3410—2016 and D6641—2014. Moreover, the experiments for optimizing the test conditions demonstrate that the strengthening tabs have a noticeable effect on the measured compressive properties for the high-performance carbon fiber composites. Accordingly, tabs made of metal are suitable for composite materials with strong interfacial bonding and high fracture strength; while tabs made of glass fiber reinforced polymer are suitable for those with weak interfacial bonding and low fracture strength. From the images of the fracture appearance of the specimens, it is observed that there are typical failure modes of ‘kinking band’ of the fibers for both the shear-loaded method and the end-loaded method. Therefore, the end-loaded compression method is a preferable method for determining the compressive strength of the composite materials, considering the measured results and failure modes.
