Features of Radial Density Distribution During Radial Isostatic Compacting of Powders

  • THEORY AND TECHNOLOGY OF FORMING PROCESS
  • Published:
Powder Metallurgy and Metal Ceramics Aims and scope

The density distribution over the radius of porous permeable hollow cylinder produced by radial isostatic compacting is analyzed and calculated. The factors promoting an inhomogeneous density distribution in porous permeable materials during this type of compacting are determined by analytical calculations. It is proved that the optimal pore distribution across the section of porous permeable material providing maximum operating properties can be obtained by using the compacting procedure that allows relating the structural properties of the material with principal operating modes.
