Abstract:

Systems and methods for flash forging a part, where a first portion of the forging seam is substantially free from grain flow pattern exit points and a second portion includes grain flow pattern exit points. In one embodiment, blocker steps are performed with pressure being applied in a first direction. A finisher step is then performed with pressure being applied in a second direction. In the blocker steps, a first portion of the part is formed without flash by extruding metal into one of the dies. The extruded shape is near the final desired shape of the first portion. In the finisher step, the first portion is pressed between two dies to achieve its final shape without producing a substantial amount of flash. Because there is no substantial flash, grain flow pattern exit points will not be produced when flash is trimmed from the part.
