Abstract

The current study attempts to compare the results of macrorheological and empirical approaches to the compaction kinetics of powdered materials and discusses the physical concepts of a regular compaction mode. Using analytical solutions of the problems on uniaxial compression and extrusion of viscous compressible materials, an equation for the compaction kinetics is derived with regard to the initial density difference. The equation is compared with Ivensen's empirical equation obtained on the basis of analyzing extensive experimental data on sintering of real powdered bodies. A physical interpretation of the results of such comparison is given, and physical views of a regular compaction mode in high-temperature deformation of powdered materials are discussed.
