Grain flow material
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.

WebMacroetch test to ASTM E340 is the controlled surface etching of a metal or alloy sample to reveal a structure such as grain flow lines and ingot patterns that are visible at the low magnification. WebOct 24, 2024 · Grain size distributions for all debris flow source material samples; labels for each correspond to sample locations shown in Fig. 1. Samples exhibit the most similarity in their content for grain sizes of silt and smaller (< 60 μ m). A strong peak in the fine sand range (~ 200 μ m) is present for all samples.
WebGrain flow is a directional orientation of metal grains and any inclusions that have been deformed by forging. Individual grains are elongated in the direction of the metal flow or plastic deformation. More importantly, nonmetallic inclusions, particles and other imperfections inherited from the casting process ( forging vs casting) are ...
