Abstract
High velocity compaction(HVC)technology was put forward by Hgans AB company,Sweden in 2001 and carried out on HVC machine produced by Hydropulsor company,Sweden with the compaction velocity no greater than 10 m·s-1.By the propagation of the stress wave through the powders,densification of the powders was realized.Due to the advantage of high and uniform density,excellent mechanical properties and capability of multiple impacts,this technology attracted more attention.The researchers in the world carried out the investigation on various kinds of powders such as iron,copper,titanium and the alloys,magnetic and ceramic materials.The densification mechanism of HVC is waiting for further study.
