“…Since the availability of the CA model can be applied in a large scale, investigation on the microstructure evolution under the situation similar to industrial casting processing with different casting parameters was performed in ref. [27] for the same strip casting process. These results showed the numerical simulation methods are a remarkably potential and convenient key to gaining insight in the microstructure evolution during casting.…”

The mesoscopic modeling developed rapidly in the past three decades is a promising tool for predicting and understanding the microstructure evolution at grain scale. In this paper, the recent development of mesoscopic modeling and its application to microstructure evolution in steels is reviewed. Firstly, some representative computational models are briefly introduced, e.g., the phase field model, the cellular automaton model and the Monte Carlo model. Then, the emphasis is put on the application of mesoscopic modeling of the complex features of microstructure evolution, including solidification, solid-state phase transformation, recrystallization and grain growth. Finally, some issues in the present mesoscopic modeling and its perspective are discussed. microstructure evolution, steel, phase field, cellular automaton, Monte Carlo Citation:Xiao N M, Chen Y, Li D Z, et al.

“…b) Only one study has been reported on microstructure formation during twin roll casting using cellular automaton-finite element (CAFÉ) [218] but that is not aimed at BMGMCs, is carried out using commercial software package and does not involve any mathematical modelling at the back end. Software embedded (nucleation and growth and heat transfer) models are used only.…”

Despite a wealth of experimental studies focused on determining and improving mechanical properties and development of fundamental understanding of underlying mechanisms behind nucleation and growth of ductile phase precipitates from melt in glassy matrix, still, there is dearth of knowledge about how these ductile phases nucleate during solidification. Various efforts have been made to address this problem such as experiments in microgravity, high resolution electron microscopy and observation in synchrotron light after levitation but none have proved out to be satisfactory. In this study, an effort has been made to address this problem by modelling and simulation. Current state of the art of development, manufacturing, characterisation and modelling and simulation of bulk metallic glass matrix composites is described in detail. Evolution of microstructure in bulk metallic glass matrix composites during solidification in additive manufacturing has been presented with the aim to address fundamental problem of evolution of solidification microstructure as a result of solute partitioning, diffusion and capillary action. An overview is also presented to explain the relation of microstructure evolution to hardness and fracture toughness. This is aimed at overcoming fundamental problem of lack of ductility and toughness in this diverse class of materials. Quantitative prediction of solidification microstructure is done with the help of advanced part scale modelling and simulation techniques. It has been systematically proposed that 2-dimensional cellular automaton (CA) method combined with finite element (for thermal modelling) tools (CA-FE) programmed on FORTRAN  and parallel simulated on ABAQUS  would best How to cite this paper: Rafique, M.M.A. (2018) Modelling and Simulation of Solidification Phenomena during Additive Manufacturing of Bulk Metallic Glass Matrix Composites (BMGMC)-A Brief Review

“…Twin roll thin strip casting and rolling technology (TRSC) is considered to be a very promising steel manufacturing technology. [1] Molten metal flows into the molten pool consisted of side dams and casting rolls from a tundish, and solidifies into steel shell on the surface of casting rolls. Subsequently, solidified shell is plastically deformed at kiss point and finally rolled into thin strip.…”

A three-dimensional numerical model was established to predict the liquid level, the temperature field, the flow field, the turbulent kinetic energy, the outlet temperature and the liquid fraction in the twin roll strip casting and rolling molten pool with side dams vibrating. The numerical simulations were also conducted to compare the flow and heat transfer characteristics under different vibration frequencies and different casting temperatures. The results showed that the heat transfer was enhanced, the mixing of solutes is optimized, the strip outlet temperatures were homogenized, the kiss lines were higher, and the rolling intervals were extended as the frequency increased. Also, excessive casting temperature would cause some unexpected problems such as liquid steel leakage and unformed strips, and also make the height of kiss line uneven. Lower casting temperature would also make the strip outlet temperature more uniform and make the kiss lines higher. Through these analyses, a new approach to advancing the development of twin roll strip casting and rolling is proposed.
