Advanced Solidification Metallurgy

Dear Colleagues,

Control of the cast structure is the underlying object of solidification metallurgy. Recent advances and developments in solidification metallurgy have made it possible to produce high purity castings for superalloys, aluminum, magnesium, titanium, and copper alloys, and rapidly solidified structural components and castings with unique microstructures. Recent advances in processing technology have also been developed that allow us to have better producibility and reliability in some metal castings. These developments have all stemmed from a good understanding of the science of solidification metallurgy, as well as an appreciation of the merits of structural control by using advanced solidification processing. In addition, numerous works have also been developed on both experimental and analytical/computer modeling aimed at disclosing the fundamental aspects of metallurgical processes, phase formation and growth within liquid melts, and numerous types of calculated software were used to clarify the solidification, such ProCAST, AnyCasting, Magma, Micress, etc.

This Special Issue of “Advanced Solidification Metallurgy” will review the latest developments in various aspects of solidification metallurgy, namely, (a) metallurgy control to composition and microstructure of metals or castings, (b) a fundamental understanding of micro and macrosegregation mechanisms, microstructural evolution of solidification microstructures, (c) multi-scale experiments and simulations for solidification by using different calculated methods, (d) fundamental aspects such as nucleation and grain growth, the development of the mushy zone, (e) thermal, compositional effects on the development/avoidance of casting defects, etc.

It would difficult to condense all of the ongoing advances in the various areas of solidification research in this brief overview. However, this issue is intended to provide a comprehensive account of the “state of the art” in the current efforts aimed at elucidating the fundamental mechanistic aspects of phase formation during solidification. Thus, all of the aspects related to recent advances in solidification fields, including metallurgy, processing, fluid flow, solute and thermal transport based on experimental, analytical, and computer simulations are welcomed in this issue.
