Web12 hours ago · Another way that forging strengthens metal is by alternating its grain structure, which is the metal material's grain flow as it deforms. Through forging, a favorable grain structure can be created, making the forged metal sturdier. ... The pounding action of forging deforms and shapes the metal, which results in unbroken grain flow. … WebJan 11, 2024 · Debris flow density is an important parameter, which reflects the genetic …
WebAbstract. Backward Erosion Piping (BEP) is an internal erosion mechanism which occurs at the down stream of dams or levees. Two conditions needed for this failure to occur: 1) head of water in the upstream of the dam or the levee to drive the seepage forces, and 2) crack in the roof or the blanket layer of the cohesionless material in the downstream of the dam … Figure 1. Grain flow can be observed in this sliced section of a forging. It has been cut, polished and etched with an acid solution. The observed flow lines are due primarily to the particles and inclusions, which were remnants of the original casting. These have been deformed during the billet conversion and … See more When examining the interior of a forging, the grain flow becomes obvious. Figure 1 shows the grain flow in a forged and machined … See more The important implication about grain flow is that some mechanical properties vary with respect to orientation relative to grain flow. This fact is one of the major benefits ascribed to forgings. … See more Content for this paper was primarily developed by Scientific Forming Technologies Corporation in partnership with SCRA Applied R&D and FIA.
