Forging porosity
WebApr 26, 2024 · The opinion, however, among men engaged in the business, seems to be that forging greatly compresses or consolidates the steel. While such is doubtless the … WebJun 30, 1998 · In an open die forging of porous materials, one can actually follow the average value of the porosity. This, in general, may not be enough for design purposes. A spatial distribution of the porosity is much more informative, since a ‘weak spot’ in the volume (i.e. an occasional domain with large porosity) may trigger a failure.

The original cross-section divided by the final cross-section is the forging ratio (say 3:1). There is an equivalent reduction on upsetting for forgings being upset during forging (gear blanks, …
WebIn general, forging produces parts that with excellent mechanical strength, impact strength, shear strength, and wear resistance. This is due to the high pressure the raw metal materials are put through and the resulting deformation, which causes metallurgical recrystallization and grain refinement that conforms to the part shape.
