High velocity compaction of aluminum powder metallurgy alloys

近净成形工艺是制造产品的替代方法，它提供最小的原材料损耗，几乎不需要二次加工或精加工。粉末冶金(PM)技术是最流行的近净成形工艺之一，将粉末金属压制成复杂的产品几何形状。高速压制是一种新兴的粉末冶金技术，它以接近20m/S的速度压制粉末，这种技术有可能以与传统压制技术相对相同的成本产生接近均匀的密度。在过去的十年中，HVC的研究已经从基本的实验试验加速到对其潜在性能改进的更深入的调查。然而，这些活动主要集中在欧洲的研究中心。作为一项新兴技术，HVC可能被证明是一种重要的具有竞争力的制造技术，拟议的研究计划旨在对加拿大PM运营产生重大影响。

Near-net-shape processes are alternative methods of manufacturing products which provide minimal raw material wastage and little need for secondary machining or finishing. Powder metallurgy (PM) technologies are some of the most popular near-net-shape processes, where powdered metals are pressed into complex product geometries. High velocity compaction (HVC) is an emerging PM technique which presses powders at velocities approaching 20 m/s. This technique can potentially produce near-uniform densities for relatively the same cost as conventional compaction techniques. The HVC research has accelerated from basic experimental trials to more in-depth investigations of its potential performance increases in the last decade. However, these activities have been centered primarily in European research centers. As an emerging technology, HVC may prove to be a vital competitive manufacturing technique and the proposed research program aims to have a significant impact on Canadian PM operations.
