Development of high velocity compaction technology in powder metallurgy

粉末冶金高速压制技术的研究现状及展望

This paper gives a brief introduction on the characteristics and status of high velocity compaction .

主要介绍了高速压制技术的特点和研究进展。

Hydropulsor AB,Sweden,has solved the facility problem that restricted the industrial application of high velocity compaction(HVC) technique after it manufactured and sold its unique hydraulic impactor,which will certainly speed up the development of the HVC technique greatly.

瑞典Hydropulsor AB制造并出售其独创的液压冲击机后,解决了长期以来限制高速压制技术工业化应用的设备问题,使该技术得到极大的推动。
