Effect of Process Variables on Microstructure, Flow, and Tensile Properties of Nickel‐Based Superalloys with Designed Porous Structures Manufactured by Laser‐Based Powder Bed Fusion

The nickel-based superalloys Haynes 282 and Inconel 625 are processed using laser-based powder bed fusion of metals (PBF-LB/M) to manufacture designed materials (DMs) with configurable open-porous morphology. Such structures can be utilized in large gas turbines, for example, as high-frequency dampers, heat exchangers, transpiration cooling features. This research investigates the effects applied volume energy input laser deflection angle (as calculated by position) on macro- microstructure tensile flow properties DMs made from 282. Furthermore, a novel combination cubic lattice has been investigated regarding potential improvements. substantial interface between two features, DM structure, is visually analyzed microcomputed tomography. analysis hierarchical reveals that manufacturable benefits terms mechanical strength while having less significant properties.
