In this study, nickel base alloy superalloy with nano yttrium oxide as Reinforcing particles, wasconstructed. The construction method used here is first performed on this superalloy. In this method,polymers are used to aid in the process of deformation of superalloy powder.The weight ratio of metal topolymer is 93 to used. First, the powder of this superalloy from the primary powders was synthesized bymechanical alloying And then combined with the polymers. After the raw material is made, polymers andbinder are removed from the sample by thermal method up to 450 C. The sample was then sintered in avacuum fernace at 1250 C. Scanning electron microscopy imaging, X-ray diffraction, and Ferritometeranalysis were used to evaluate the properties of sintered samples The Archimedean Density Method wasused to check relative density of components. The samples had relative density of above 90% oftheoretical density. The results showed that the components made from this method have the same densityand hardness as the samples produced by the conventional synthesizer method With the difference thatusing polymer binders, it is possible to make large parts. It is also cheaper than other methods.
