摘　　要：高速压制(HVC)技术是一种高效率、低成本制备高性能粉末冶金零件的新技术.综述了HVC技术的研究现状,探讨了HVC技术的致密化机理,指出质量能量密度是较峰值压力和冲击能量等更适合HVC技术特点的科学表征方式,进一步展望了HVC技术的发展趋势.High velocity compaction （HVC） is a recently developed technology for foming high density metallic parts with high efficiency and low cost.Progress in developments of HVC technology is reviewed,and its densification mechanism is discussed.Impact energy per unit mass is more suitable to characterize the features of HVC technology than conventional peak pressure and impact energy.Development trend of HVC technology is prospected further.

关 键 词：高速压制(HVC) 粉末冶金 致密化机理 质量能量密度
