摘要 Advancements in metallurgical technology have led to the emergence of high-performance requirements for metal materials, like high uniformity, high purity, and superfine crystallinity. This has resulted in the development and application of internal cooling source (ICS), vibrational, and vibrational internal cooling source methods in metal solidification processes to afford products with refined crystal grains and large proportions of equiaxed crystals. These methods have gradually been introduced into laboratories and some steel mills over the past few decades. However, there are few successful industrial applications of these methods, as there is no comprehensive understanding of their control theories and principles. Accordingly, the development, basic principles, and classifications of the three types of methods are summarized, and their impact on the solidification of molten metals and the morphology of solid products is discussed. In addition, experimental and numerical simulation-based researches on each type of method are reviewed and their prospects for applications are briefly discussed to control metal solidification. Finally, detailed future perspectives are provided on vibratory strip feeding, ICS, and pulsed magneto-oscillation methods. Hopefully, it will serve as a reference for future studies of the application of these and related methods in metal solidification processes.
