Special Issue Information

Dear Colleagues,

Additive Manufacturing (AM) represents a revolutionary approach to manufacturing, offering unparalleled flexibility in the design and fabrication of parts and components. Contrary to being a single method, AM encompasses a range of methods based on the common principle of layer-by-layer fabrication from a computer-aided design (CAD). In addition to its design flexibility, AM techniques can process a variety of materials, including polymers, metals, and ceramics, and even pave the way for the use of novel composite materials with tailored properties for different applications. However, as a relatively nascent field, AM presents a host of challenges alongside its numerous opportunities and capabilities.

This Special Issue (SI) aims to feature research and review articles that shed light on the various aspects of AM technologies and their real-world applications. A particular emphasis, though not exclusive, will be on the in-depth study and analysis of innovative AM methods, the unique material properties attained post-manufacturing, and their impact—positive or negative—on the functionality of the end product. The SI will also welcome articles exploring novel design concepts and lightweighting strategies to enhance both design efficiency and part functionality. Another area of keen interest is the development of numerical and analytical methods for modeling and simulating AM processes. Robust and consistent modeling and simulation are crucial for deepening our understanding of the underlying physical mechanisms governing AM processes. Through the use of these models and meta-models, further process optimization and advancements can be realized.

It is my great pleasure to invite everyone to submit a manuscript for this Special Issue. Full papers, communications, or reviews on Modelling and Applications for Additive Manufacturing are welcome.

The Hazelett continuous casting and rolling process represents a leading-edge production method for cold-rolled aluminum sheet and strip billets in the world. Its solidification microstructure significantly influences the quality of billets produced for cold rolling of aluminum sheets and strips. In this study, employing the CAFE (Cellular Automaton—Finite Element) method, we developed a coupled computational model to simulate the solidification microstructure in the Hazelett continuous casting process. We investigated the impact of nucleation parameters, casting temperature, and continuous casting speed on the microstructural evolution of the continuous casting billet. Through integrated metallographic analyses, we aimed to elucidate the controlling mechanisms underlying the Hazelett continuous casting process and its resultant microstructure. The results demonstrate that the equiaxed rate of grains increases with an increase in nucleation density, and the grain size decreases under constant cooling strength. With other nucleation parameters held constant, the grain size decreases as undercooling increases, and the columnar crystal zone expands. The nucleation density of the Hazelett continuous casting aluminum alloy has been determined to range between 1011 m−3 and 1013 m−3, and the undercooling ranges between 1 °C and 2.5 °C. The solidified grain structure can be controlled between 35 μm and 72 μm. The grain size of the continuous casting billet increases with an increase in pouring temperature and decreases as the casting speed increases. Elevating the pouring temperature positively impacts the fraction of high-angle grain boundaries and promotes the dendritic to equiaxed grain transition. Moreover, there exists potential for further optimization of continuous casting process parameters. Full article
