Forging discontinuities
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. WebThere are four basic forging processes: 1) impression die, 2) open die, 3) seamless rolled ring, and 3) cold forging. Open die forging can trace its history to the original blacksmith shop of hammers and presses. Open die forging is a controlled plastic deformation process, which improves overall mechanical properties of the workpiece.
