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.

Recovery of fatigue and manufacturing damages by electropulsing treatment

Thu, 23 Nov 2023 00:00:00 GMT

Title: Recovery of fatigue and manufacturing damages by electropulsing treatment Authors: Chang, ITH; Cai, Q; Zhou, M; Assadi, H Abstract: Metals are vital to human society and have widespread uses across a broad spectrum of industries including but not limited to packaging, transport and construction applications. They are mainly used in load-bearing structural components. Nonetheless, they possess finite operational lifetime attributable to the dynamic interplay of environmental and mechanical stimuli, culminating in the generation of structural imperfections, deterioration, and the ultimate mechanical failure. It is estimated that metal fatigue is responsible for more than 80% of mechanical failure due to the existence of flaws such as cracks. Consequently, there is an imperative to pioneer advanced materials technology with the express aim of extending the operational lifetime of metallic components. This endeavour not only serves to increase material resource efficiency but also serves as a bulwark against environmental damage. ...
