Dear Colleagues,

Metal materials need to undergo one or more solidification processes to form the final product, during which microstructure and composition distribution are formed. The microstructure and composition distribution are formed in the solidification process, which to largely determine the choice of subsequent processing means and technology, and have a decisive influence on the performance of the metal. Therefore, the theory of metal solidification is of great significance for the optimization of material performance, and it is the subject of common concern of metallurgical materials discipline.

Pressure has significant effects on physical and chemical properties of metals, heat transfer, grain nucleation and growth, solubility of gases and volatile elements, solidification thermodynamics and kinetics, shrinkage porosity and pore defects. Pressurized metallurgy is a promising special steel smelting method. At the same time, due to the high solidus and liquidus temperatures of steel, especially in the process of pressurized metallurgy, strict technical requirements are put forward for experimental equipment and conditions. Therefore, computer simulation is also widely used to study the pressurized solidification process. We try to provide some new insights into the solidification theory of pressurized metallurgy by experimental methods and calculation methods.

In this Special Issue, we seek to provide a wide set of articles on various aspects of solidification in metallurgical process. It is hoped that this open access special issue will provide a place for anyone to familiarize themselves with the current state of metal solidification. Articles on the solidification process of steelmaking are desired, such as grain nucleation and growth modeling, calculation of heat transfer between ingot and mold interface, modeling of multiphase flow model, motion behavior of inclusion particles by means of the deformable part model (DPM), preparation of new techniques of high-quality special steels based on compression solidification theory and development of new varieties, and so on.
