چکیده
Electrochemical machining (ECM) is an effective method for machining CMSX-4 superalloy, a single-crystal nickel-based superalloy, due to its unique performance in metal machining. The microstructure of this superalloy consists of three phases: gamma (γ), gamma prime (γ'), and carbide. The gamma prime phase is distributed cubically and homogeneously in the gamma field without any boundaries. It is essential to maintain this microstructure after the production process. In the present study, ECM was performed on a CMSX-4 superalloy workpiece. The microstructure of the workpiece was then investigated before and after ECM using scanning electron microscopy and energy-dispersive spectroscopy analysis from two sides. The results showed that no changes were observed in the CMSX-4 microstructure after ECM process. The single-crystal structure and the distribution of the gamma prime phase were maintained after this machining process, indicating that ECM is an effective machining method for CMSX-4 superalloy without compromising its critical microstructural features.
