The process of sintering in FeAl2-Ni-Fe system (Al 12%, Ni 25%, Fe 63%) is discussed in this paper from the experimental stand-points; i.e. the dependence of various properties (density, electrical resistivity, microstructure) upon the sintering process of water-quenched specimens from their sintering temperature has been investigated. The conclusions obtained were as follows: (1) At the sintering temperature of 700°C, a decrease down to 1/26-1/58 of the green compacts in electrical resistivity at was already observed, suggesting that the diffusion of the components has set in . (2) When the sintering temperature reached 1250°C, rapid alloying of component particle, i.e. the reactions of FeAl2 phase+Ni phase→α′ phase, and α′ phase+Fe phase (γ)→α phase have been observed, and after sintering at 1350°C for 90 min the specimens consisted of α phase only. (3) The effect of compacting pressure upon the sintering process of the FeAl2-Ni-Fe system where no liquid phase is was existence has been found to be larger than that when a liquid phase was in existence. (4) The effect of sintering temperature upon the sintering process of the FeAl2-Ni-Fe system has been found to be larger than that of sintering time.
