Abstract

Superalloys have been used for aerospace application because of their excellent attributes of high strength, corrosion and oxidation resistance at high temperature. Rene95 is one of representative Ni based superalloys. However, it is not easy to produce the complicated parts at low cost due to their poor workability. It is also difficult to use a casting because of segregation during the process. Metal Injection Molding (MIM) process, one of near net shape forming of powders, has been applied to fabricate the Rene95 parts. In the present work, nearly full dense compacts were obtained by optimizing the process parameters of MIM. Tensile strength of the heat treated MIM compacts was over 1400 MPa, which was similar to the HIPed materials' one. High temperature strength at 700°C was 1177 MPa. The strength decreased by just 16 % from room temperature.
