Abstract

The debinding process of injection-molded compacts of Fe–8Ni mixed powders, containing binders of different ratios of polymers to wax, was investigated. The effect of binder compositions and debinding conditions on the sinterability of the compacts were also studied. Distortions produced in the debinding processes of the compacts were minimized for the case where a ratio of polymer to the total binder contents was 0.35. In the case of the compacts debound in air, sintered densities increased by increasing the debinding temperature up to 350 °C, then decreased sharply for higher debinding temperatures. In the compacts debound in N2, sintered densities were almost independent of the debinding temperature. The sinterability of the compacts debound in N2 was inferior to that debound in air.
