| Abstract Scope |
In the recent years, additive manufacturing has manifested itself as an unparalleled fabrication technique for Inconel 718 parts employed in aerospace, process, oil and gas industries etc. The rapid solidification and the repeated heat incidence during the DMLM process significantly affects renders drastic properties changes. Literature delineates a vivid gap in the efforts to capture the coherent relationship between process parameters and material performance characteristics in a production environment. The current research is an endeavor to cement the gap by studying the effect of process parameters-laser power, laser scan speed, hatch spacing, layer thickness on the, tensile strength and fracture toughness. The goal is to optimize the material performance under the conditions of improved production rate parameters such as layer thickness and laser scan speed. The research will present the trends of the process – structure – property- performance relationships and optimal parameters for processing in a production environment. |
