Abstract This chapter discusses the methods by which stainless steel powders are shaped and compacted prior to sintering, including rigid die compaction, metal injection molding, extrusion, and hot isostatic pressing. It explains where each process is used and how processing parameters, such as...

... Vacuum is used to draw the metal into the mold cavity in an effort to produce very thin-walled castings. A vacuum manifold is built over the top mold, and vacuum is applied through sinter vents. The ejector pins need to be sealed against vacuum leaks by high-temperature-resistant gaskets. Their provision...

Another method is to consolidate the blend in a can to about 95 percent density by hot pressing, and then...
