%X Ferrous parts were prepared through high velocity compaction(HVC),the relationship between the impact energy,the impact velocity and the stroke length was investigated.The effects of impact energy and compaction methods on the green density,the maximal impact force,the withdraw force and the radial springback were discussed.The results showed that the impact energy was direct proportional to the stroke length and the impact velocity is parabolic to it.The green density increased with the impact energy increasing.In single impact the green density was 7.336 g/cm~3,relative density about 97%,when impact energy was 6510 J.For the same total impact energy the green density of specimen processed by double impacts was the best and that of specimen fabricated by triplex impacts was the lowest.The withdraw force and the radial springback of specimen produced by HVC were all lower than that of specimen processed by traditional compaction.
