| Abstract Scope |
Multicomponent powder beds are being actively explored to address common issues in additively-manufactured aluminum parts such as hot cracking, pore formation, and surface oxidation. In particular, we will discuss the modeling of multicomponent Al-Zr powder beds for light-weight aluminum alloys. Multiphysics models are often used to investigate the underlying physics controlling AM processes using high-fidelity simulations of individual powder melting into the substrate. Here, we will present a novel multiphysics-multiphase model to simulate multicomponent powder beds during AM process. A convection-diffusion formulation for component fraction, in conjunction with the Navier-Stokes equations and a new enthalpy form of the energy equation, enable us to understand the phase evolution in multicomponent beds and the dispersion of solute metals in the melt pool during the process. Results of the presented models will be discussed and compared with available experimental data from literature and our collaborators. |
