High density PM parts by high velocity compaction

High velocity compaction (HVC) is a mass production technique with the capa city significantly to improve the properties, and hence expand the applicat ions, of both PM structural parts and soft magnetic composites. The process developed by Hoganas can produce high density components (7.4-7.7 g cm(-3) for prealloyed and diffusion alloyed grades) exceeding 5 kg in weight at h igh production rates: the initial compaction stage takes < 20 ms. An overvi ew is given of the process and its capabilities, and potential applications are discussed.
