Forging is the process of shaping metal through the use of compressive force, causing plastic deformation of the piece, most often accomplished with the use of a hammer or die. Forgings may be hot or cold processed depending on the raw materials and the requirements of their application. Pieces can range in size and can be anywhere from a …
Webof surface discontinuities 3.1 Cracks A Crack is a clean (crystalline) fracture passing through or across the grain boundaries and may possibly follow inclusions of foreign elements. Cracks are normally caused by overstress- ing the metal during forging or other forming operations, during heat treatment. WebAlready, there are some discontinuities in the forging process. Hydrogen is picked up during the heating process and it segregates at those discontinuities and internal voids and flakes are produced. Another …
