Abstract

The ceramics(h-BN) core was applied for the Pulse Discharge Pressure Sintering (PDPS) method in order to consolidate the hollow shaped compact of the aluminum alloy powder(A 2014) and nickel alloy powder(Alloy 625).
The densities of these compacts were 2.78 g/cm³ and 8.41 g/cm³, respectively. These values correspond to the densities of solid compacts which were sintered by PDPS without using the ceramic core.
This method can be applied for the consolidation of complicated shape hollow compact like gear, tools etc, .
