Waveguide Method for Surface Impedance Measurements on Composite Material Substrates

2026-08-10T11:43:54Z

Title: Waveguide Method for Surface Impedance Measurements on Composite Material Substrates Authors: Fakis, Dimitrios I; Worrall, Chris; Kazilas, Mihalis Abstract: A novel method has been introduced for measuring the surface impedance of composite material sheets at microwave frequencies. A length of circular waveguide is manufactured using the fibre-reinforced composite material and its scattering parameters are measured with the use of a network analyser (VNA). An iterative simulation method is subsequently used for the derivation of the surface impedance of the composite based on altering the impedance boundary condition on the walls of a precise model of the waveguide, as manufactured, until the simulation results for its scattering parameters match the experimental values.

Mathematical modeling of grain fragmentation induced by flow shearing in high-pressure die casting of light alloys

Title: Mathematical modeling of grain fragmentation induced by flow shearing in high-pressure die casting of light alloys Authors: Lu, J-Z; Dou, K; Zhang, Y-J; Lordan, E; Jacot, A; Fan, Z; Wang, W-L Abstract: In the cold-chamber high-pressure die casting (CC-HPDC) process for light alloys, strong shear stress generated by the fast-flowing melt through narrow runners breaks externally solidified crystals (ESCs). Two runner configurations were applied in the CC-HPDC process of aluminum alloy to address this problem. A comprehensive finite element model was established to calculate shear stress in the runner regions during die filling, and a novel mathematical model of grain breakup was proposed to quantitatively analyze ESCs fragmentation through different runners. Particles ranging in size from 12.2 to 16.1 μm constitute a significant proportion of the ESCs and serve as the primary focus of subsequent shear fragmentation. Finally, HPDC test trials validate the mathematical model by characterizing grain morphology and size distribution in as-cast samples and the error of the model is less than 20%. The results demonstrate that the novel model is highly effective for the design of runner systems and the optimization of process parameters in the CC-HPDC process for light alloys.

Solid/liquid interface energy and its anisotropy of pure metals

Title: Solid/liquid interface energy and its anisotropy of pure metals Authors: Fan, Z; Men, H Abstract: Solid/liquid (S/L) interface energy (𝛾_sl) and its anisotropy (φ) play a critical role in the understanding of nearly every single phenomenon that occurs during solidification of metals, such as nucleation, morphological instability and dendrite growth. However, due to difficulties associated with both experimental measurement and computer simulations, our current understanding of this topic is rather limited. In this work, a simple analytical model is developed to predict 𝛾_sl and φ for pure metals. This model suggests that S/L interface energy originates from atomic ordering in the S/L interface templated by the solid. 𝛾_sl can be expressed as the sum of contributions from both atomic layering (𝛾_z) and the in-plane atomic ordering ((𝛾_xy). Further analysis shows that 𝛾_sl for pure metals is determined by both heat of fusion per atom (∆𝐻_f) and their crystal structures, while anisotropy depends only on crystal structure. The analytical model reveals that the physical origin of 𝛾_sl is atomic ordering in the S/L interface templated by the solid, while the physical origin of anisotropy is the difference in structural templating power between different crystal planes. It is demonstrated that the current analytical model is capable of predicting solid/liquid interface energy (𝛾_sl) and its anisotropy (φ) for any metallic element using parameters readily available in the literature.
