| Abstract Scope |
Metal additive manufacturing (AM) microstructures vary depending on the processing parameters, geometry, and printer platform. This diversity of as-built microstructural features across an alloy makes designing a single optimum heat-treatment procedure difficult. Computational modeling can be used to design optimum heat-treatments for AM metals, but there has been little validation of these models. In this work, the impact of the starting microstructure of Haynes 282 on the response to homogenization heat-treatment is investigated. Samples were made using wire arc directed energy deposition (DED-Arc) and the elemental segregation was characterized. To simulate the heat-treatments, diffusion was simulated using a five-point stencil on the composition maps and ThermoCalc tracking the incipient melting temperature’s evolution. These samples were heat treated and recharacterized to determine extent of homogenization. The simulation predictions were validated against the experimental results to determine if this model can be used for homogenization heat-treatment optimization in the future |
