A densification equation for a commercial water-atomized 316L stainless steel powder mixed with 1 wt.% lubricant was derived from deformation occurring in the powder mix during cold compaction, and experimentally verified through compaction tests to produce specimens with different geometry, green density, and particle-size distribution. In contrast to other densification models reported in the literature, the newly proposed densification equation highlights the influence of the variables investigated on the resistance of the powder mix to densification.

Abstract
A densification equation for a commercial water-atomized 316L stainless steel powder mixed with 1 wt.% lubricant was derived from deformation occurring in the powder mix during cold compaction, and experimentally verified through compaction tests to produce specimens with different geometry, green density, and particle-size distribution. In contrast to other densification models reported in the literature, the newly proposed densification equation highlights the influence of the variables investigated on the resistance of the powder mix to densification.| File | Dimensione | Formato | |
