Abstract

The MIM418 superalloy was prepared by metal injection molding using master alloy technique. The influence of heat treatment on microstructure of MIM418 alloy was discussed in this paper. The relative density of the sintered specimens reaches 96%. Homogenous microstructure is achieved after solution treatment at 1200°C for 4h. The sphere secondary γ′ phase is about 0.1 µm and distributes uniformly in the grain. The aging temperature of 750°C is suitable for the MIM418 superalloy due to the slow coarsening rate and non-significant morphology change of precipitated phases.
