A Ni-based superalloy is widely used in many industrial field because of their high performance which is unusual class of metalic materials with an exceptional properties (high temperature strength, toughness, stress, oxidation/corrosion resistance). So, the most important application of Ni-superalloy is aircraft engines (gas turbine, turbine blade, etc), gas turbines for power generation and other challenging environments such as nuclear power and chemical plants. In the future, according to increasing the demand, amount of waste turbine blade is expected to be discarded. Therefore, it is necessary to research about recycling technology of waste Ni-based superalloy. In this study, we focused our research on the possibilities of recycling using waste Ni-based superalloy by AOD (argon-oxygen decarburization) process. Also, we were investigated experimental changes including Ar or O2 flow rate, reaction time, voltage to obtain the data of element component and structural changes. So, we evaluated the possibility about recovery of Ni or other metals.
