PLASTIC DEFORMATION IN MATERIALS …

plastic deformation to be expected for each materials process. 1. Introduction Plastic deformation occurs when a material is stressed above its elas-tic limit, i.e. beyond the yield point, as illustrated in Figure 1. The resulting plastic deformation is permanent and cannot be recovered by simply removing the stress that caused the deformation. The …

Forging is a Bulk Deformation Process in which the work is compressed between two dies. According to According to the degree to which the flow of the metal is constrained by the dies there are three types of forging:

Design of Forming Processes: Bulk Forming

The bulk deformation process of forging is an example of a continuous-flow process. As the metal is being shaped in the forging die cavity, the deforming region, which is often the entire amount of metal, is continuously undergoing change. Processes such as rolling, wire drawing, and extrusion are exam-ples of quasi-static flow. For example, in rolling, the deformation …
