| Abstract Scope |
Components manufactured by powder bed fusion (PBF) frequently have a strong crystallographic texture that can cause anisotropic material properties. However, studying the role of phase-change characteristics, like the enthalpy of fusion and freezing range, on crystallographic texture development is difficult using experimental approaches. Process-structure (PS) simulations provide one avenue for studying these phenomena and a pathway to influence and control the resulting crystallographic texture. However, the trade-offs between temperature field accuracy and the computational cost of including robust phase-change characteristics in PS simulations are poorly quantified. This work uses the “Materialite” software package to simulate PBF temperature and microstructure evolution at varying values for the enthalpy of fusion and freezing range in nickel-based aerospace alloys. This study will quantify the sensitivity of the temperature field, melt pool geometry, crystallographic texture, and computational cost to phase-change characteristics during PBF simulations and inform the relative importance of simulation parameters. |
