Summary

Structure and physical properties of molten metals. The principles of metal flowing, pressure conditions in gatings. The running property of liquid metals and alloys and their coherence with the design of castings. The thermal and physical processes in a casting and in a mould. Interaction between casting and mould. Crystallization and solidification of castings.
