Processed through the forging of metal to improve its organizational structure and mechanical properties. Casting forging method through the metal after hot working deformation deformation and recrystallization, so that the original coarse dendrites and columnar grains become finer grain size and uniform equiaxed recrystallized to the original segregation within the ingot, loose, porosity, slag and other compaction and welding, the organization more closely to improve the mechanical properties of metal and plastic.

In general, lower than the mechanical properties of casting materials mechanical properties of forgings. In addition, the forging process to ensure the continuity of metal fibrous tissue, so that forging the shape of fibrous tissue consistent with forging, metal flow line integrity, and can ensure that parts have good mechanical properties and long service life with precision forging, cold extrusion , produced by warm extrusion processes such as forgings, castings are unmatched.
