Abstract Scope |
Inconel 718 (IN718) is a nickel-based superalloy used in aerospace and oil industry due to its superior high temperature mechanical properties , corrosion resistance, fatigue resistance, and weldability.. Laser powder-bed fusion (LPBF), a rapidly growing additive manufacturing technique is capable of fabricating complex metals parts with controllable properties. The properties of metal parts produced via LPBF are highly sensitive to the process parameters due to complex thermo-fluid interactions. Hence, optimizing the process parameters is crucial to enhance the reliability of LPBFd parts. This study investigates the effect of laser power and scan speed on the microstructure and mechanical properties of as-built IN718. Optimal processing conditions are identified for achieving high density, microhardness, ultimate tensile strength, and ductility. |
