234 放電プラズマ焼結法による機能性複合材料の作製(OS 高エネルギー加工(2))

抄録

The present paper refers to experimental study of the powder mixture of wood charcoal, iron and copper followed by spark plasma sintering. A composite molding technique is applied to the compression molding of different type of powders at a constant heating temperature and forming pressure. The main factors affecting the sintering and bonding of different substances include temperature and pressure. It was found that Fe/Cu/Carbon powders can be heated fast and sintered in very short time: ISminutes at the temperature range of 820℃ to 990℃ using spark plasma sintering. The investigation on manufacturing of functionally composite materials is summarized above and it is evident that more work using different approaches is necessary.
