![]() ![]() Multi-physics simulations were conducted using Truchas for STLF by considering heat transfer, phase-change, fluid dynamics, surface tension phenomena, and evaporation. As a critical step towards fully LPBFAM modeling, modeling of single-track laser fusion (STLF) were conducted. In this project, a multi-physics model was developed on a highly parallel open-source code, Truchas, with the ultimate goal of providing experimentally validated process maps for tailoring microstructure to achieve desired performance for LPBFAM. At present, the cost and time associated with LPBFAM process development is very high due to a lack of fundamental process understanding. The Laser Powder Bed Fusion Additive Manufacturing (LPBFAM) is one of the most important processes for the production of lightweight, cost-effective, complex, and high-performance enduse parts. ![]()
