Abstract Scope |
The Ni-based Ni48(CrAlFe)15Ti7 and Ni48(CrCuFe)12.5Al7.5Ti7 medium entropy alloys were designed by Thermocalc software and fabricated using arc suction casting method having Ti-guttered in an argon atmosphere. The effect of Cu element on phase evolution, microstructure, and mechanical characteristics was investigated. Detailed characterization reveals that the alloys exhibit dual microstructures consisting of BCC dendrite and FCC interdendritic in Ni48(CrAlFe)15Ti7 alloy meanwhile, rectangular shape morphology (γ + γ՛ phases) in Cu addition Ni48(CrCuFe)12.5Al7.5Ti7 alloy. The result of the mechanical property test illustrates that alloys present outstanding strength at a high-temperature range compared to Inconel 713C and excellent ductility with the microstructure of γ + γ՛ phases. |
