Abstract

Powder morphology affects the compacting behavior as well as the packing and the fluidity of powder. A quantitative analysis was carried out by evaluating the correlation between the compacting behavior and the morphological properties of metallic powder. The compacting behavior was quantified with the equation proposed by Cooper and Eaton, which expresses the behavior with two mechanisms of rearrangement and plastic deformation of powders. The powder morphology was characterized with the particle size-shape dispersion diagram. The rearrangement behavior of powder was quantitatively related with four factors of the morphological properties by using two linear equations. The plastic deformation behavior was characterized with the packing density and the hardness of powder.
