127 金属粉末の連続加圧焼結法の開発(OS 粉末加工(1))

抄録

A new industrial process which enabled a continuous pressurized sintering of metallic powder was examined. A unique open mold with a shoulder in its sintering room was proposed so as to ensure suitable pressurizing to material powder in the continuous process. Tin powder was sintered continuously according to the proposed process, and it was confirmed that the pressure was worked stably to powder during sintering. This sintering brought a successful production of a tin rod which achieved the relative density of 99%. It was indicated that the proposed sintering system had the potential for continuous production of dense and homogeneous metallic rod.
