| Abstract Scope |
Gas metal arc welding (GMAW) based wire arc additive manufacturing (WAAM) offers several benefits including high deposition rates and low equipment cost to manufacture large structural components. In high temperature structural applications, such as power generation, precipitation strengthened Ni-based alloys are often used. In this presentation, we discuss our work focused on developing models capable of predicting the microstructure of WAAM Haynes 282. We combine a dendrite growth model with heat transfer simulations to predict primary and secondary dendrite arm spacing, dendrite growth morphology, and elemental segregation in the as-built condition. Methods to calibrate our models with experimental measurements are discussed. |
