概要
- 論文の詳細を見る
The sintering process of intermetallic compound NiAl, which has some properties necessary for high temperature material, that is, excellent oxidation resistance, thermal shock resistance, comparatively stable crystal structure and high melting point of 1650℃, was studied. It was seen that the distribution of particles, the oxide inclusions, the kind of binding agent and sintering atmosphere had remarkable influences on the process of sintering. The density, the porosity, the volume change, the hardness and the expansion coefficient were measured and the microscopic structure was examined. The most suitable condition for the sintering was compacting pressure of 4〜7 t/cm^2 sintering temperature of 1400〜1450℃ and sintering time of 3〜5 hrs in vacuum 10^<-4>mm Hg.
