... roll forging Flat-back dies are primarily used for short-length workpieces. They are bolted to the roll shafts and can be easily changed. Typical contours for a set of flat-back segmental dies are shown in Fig. 7 . This type of roll die allows maximum time for moving the part from one impression...

... configuration. In wire or rod drawing ( Fig. 1 ), the section is usually round but could also be a shape. In the cold drawing of shapes, the basic contour of the incoming shape is established by cold-rolling passes that are usually preceded by annealing. After rolling, the section shape is refined and...

The roll compaction process is related to dry pressing in that it uses spray-dried powders as feedstock to produce the continuous strip of tape. Its major difference is the...
