放電焼結の科学と新しい応用 Science and New Applications of Electric Discharge Consolidation
This overview describes the fundamentals of the electric discharge consolidation which provide a route to the design and development of advanced materials. The proposed intelligent sintering consists of the pulse electric discharge system, combined with the process control methodologies and the microstruture control techniques. The process control and/or model is set up for the formation of the neck between spherical amorphous particles via feeding rectangular pulses and the full densification of amorphous ceramic compact under electric field. Furthermore, the electric field controlled technique can synthesize fully dense nanograined ceramics having the plastic strain rate of 3.10<SUB>-2</SUB>s<SUB>-1</SUB> around 1350 K.
