アトマイズ法により作製された亜共晶Fe-C系鋳鉄粉末のパルス通電焼結特性(1) -焼結体の気孔率制御と内部組織- Pulse Electric Current Sintering Behavior of Atomized Cast-iron Powder of Fe-C System Containing Hypo-eutectie Carbon (1) -Porosity Control and Microstructure-
We studied the pulse electric current sintering behavior of the atomized cast-iron powder of Fe-C system containing hypo-eutectic carbon and the microstructures of sintered bodies. The results were as follows:<BR>(1) The porosity control of the atomized cast-iron sintered body, which was very difficult by the vacuum sintering method, could be done by the pulse electric current sintering method with several sintering conditions, that is, the sintering temperature and the sintering pressure.<BR>(2) The microstructure of the sintered body was depending on the sintering temperature, and was independent of the sintering pressure.
