中文摘要：

本文简述了粉末冶金高速压制技术（High Velocity Compaction,简称HVC）的基本原理、主要特点及其研究进展.HVC技术是一项低成本、高效率成形高密度（7.4～7.8 g/cm3）粉末冶金零件的新技术.粉末在0.02 s之内通过高能量冲击进行压制,通过附加间隔为0.3 s的多重冲击波将密度进一步提高.HVC技术拓展了PM成形技术的应用领域,具有广阔的应用前景.

英文摘要：

The high velocity compaction（HVC） technique in powder metallurgy is described. HVC is a new manufacturing technique, for producing high density（7.4 g/cm^3 -7.8 g/cm^3） PZM parts efficiently at low cost. Powder is compacted with- in less than 20 milliseconds by high- energy impacts. Further densification is achieved by multiple impacts at intervals of as short as 300 milliseconds. HVC expands the range of PM forming technique and is expected to have a high potential in the future.
