Shock Consolidation of Coarse Sic Powder

Abstract

Sic compacts with 98.6% of theoretical density were obtained from coarse powder by a shock compaction technique. Microhardness values for the compacts obtained at 8 and 13 GPa ranged from 15.7 to 22.5 GPa and from 21.6 to 28.2 GPa, respectively. Scanning electron microscopy suggested that small amounts of molten material participated in the shock consolidation process.
