Radial Die Wall Pressure during Ceramic Powder Compression and Unloading

概要

論文の詳細を見る
The radial die wall pressure during uniaxial powder compression and unloading processes was measured using various kinds of Al<SUB>2</SUB>O<SUB>3</SUB> powders. The radial pressure during compression increased with increasing compaction pressure linearly and decreasing BET specific surface area of the powder. The radial pressure during unloading decreased due to plastic deformation of the green pellet. The residual pressure after unloading increased with increasing compaction pressure. The residual pressure normalized by the radial pressure during compression increased with increasing BET specific surface area of the powder.
