Abstract
A new phenomenological equation for the compaction curve is given. This equation is easy to use, permits a quantitative description of the compaction process, and enables the characterisation of powder consolidation behaviour by two parameters. Based on several sets of published data on the compaction of both metallic and non-metallic powders, the results of linear regression analyses show that in most cases the proposed equation gives correlation coefficients closer to unity (usually 0·99 to 0·999).
