Web1.2 Forging defects: One of the major defects in upset forging or open die forging is the surface cracks originating on the bulged or barreled surface due to excessive tensile hoop stress. Surface cracks may be longitudinal or inclined at 45 o angle. If the circumferential stress is tensile, longitudinal cracks occur. If hoop stress is ...

WebOpen die forging is actually the first forging process that mankind has mastered. Since many open die forgings are huge it was difficult to develop the technological process economically. Forgers used to perform reduced scale size tests (e.g. 1/25 size) and use the engineer’s methods (upper-bound method, glide lines method and others) to develop the … WebAs shown in Figure 1, open-die forging is a hot forming process in which metal is shaped by hammering or pressing between flat or simple contoured dies. The forms obtained and the dimensions maintained are usually dependent upon the skill of …
