Research Progress of High Velocity Compaction Technology for High Densification of Powder Metallurgy

High velocity compaction (HVC) is an extreme extension for conventional powder pressing technology and is another breakthrough in the powder metallurgy (PM) industry for low-cost and high-density forming parts.HVC is a new manufacturing technique for producing high density (7.4-7.8 g·cm-3) PM parts efficiently at low cost (similar to conventional pressing) and it can offer multi-impacts and the opportunity to use moderately sized equipment for compacting very large components.This paper focuses on the basic principle,main characteristics and current progress of HVC.Some problems existing and research interests in the future are pointed out.
