Abstract Scope |
Recent advancements in computational materials modeling have made the development and evaluation of alloy behavior in additive manufacturing (AM) more efficient and cost-effective. These advancements have enhanced AM's ability to design targeted materials and leverage its unique processing capabilities by predicting microstructural effects and linking them to essential properties. This study introduces a solidification cracking (SC) model that incorporates both composition and fluid dynamics. The model evaluates SC susceptibility by integrating computational thermodynamics and fluid dynamics, building on concepts such as the solid/liquid interface and interdendritic fluid pressure drop. Validation of the model was performed using benchmarking and the Transvarestraint test. A novel SC indexing method, the Flow Resistance Index (FRI), is presented. The FRI measures the impact of alloying elements on cracking susceptibility across various metal systems, including aluminum alloys, austenitic SS, and Ni-based alloys. This index can be utilized for material design, optimization, and selection in AM-related applications. |
