| Abstract Scope |
Inconel 718, a nickel-based superalloy that has impressive mechanical properties such as tensile and impact resistance, as well as resistance to corrosion at high temperatures. One commonly used cellular structure is the gyroid lattice, which is a type of triply periodic minimal surface that can be customized to create lightweight materials with adequate strength and low stiffness. Selective laser melting (SLM) process has made it possible to manufacture these complex structures, and the properties can be controlled by adjusting various process parameters such as scan strategy, laser power, and build direction. However, the impact of build orientation on the properties of the lattices has not been extensively studied. This work focused on fabricating gyroid lattice structures at different build orientations, and the microstructural and mechanical properties of the structures were studied through Scanning electron microscopy and quasi-static compression tests. |
