Modeling and Mastering the Forging of Crystallizing Metal

Abstract

The rational use of metal is determined by the use of alternative methods to produce blanks, including forging a crystallizing metal. Application of external pressure to the melt during crystallization completely eliminates gas porosity, which improves the mechanical characteristics of the products, and substantially increases the crystallization rate, which improves the life of dies. The results of mathematical modeling underlie the selection of thermomechanical conditions for forging of metals (iron, steel, and aluminum alloys) that crystallize under pressure. A number of liquid metal forging processes are mastered.
