Abstract：Powder metallurgy parts with high performance can be prepared by powder metallurgy high velocity compaction economically. The density and properties of the parts are close to the powder forging， but the cost is much lower than that of powder forging. In recent years， the powder metallurgy high velocity compaction technology is combined with the technology of die wall lubrication， warm compaction or re-pressing and re-sintering， so that its application field is further broaden. The principle and application， numerical simulation and the research progress of densification mechanism of powder metallurgy high velocity compaction were summarized， and the future research directions were also pointed out.
