Research Progress of High Velocity Compaction Technology for High Densification of Powder Metallurgy
摘 要
高速压制技术是传统粉末压制成型技术一种极限式外延的结果,被认为是粉末冶金工业寻求低成本高密度材料加工技术的又一次新突破.高速压制是一项以较低成本(与传统模压一样)、高效率制备高密度(7.4~7.8 g·cm-3)粉末冶金制品的新技术,可实现多重压制,具有使用中小型设备生产较大制品的能力.简要介绍了该技术的基本原理、主要特点及最新研究进展,最后指出该技术目前存在的问题并指出未来的发展方向.

Abstract
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.
