Abstract Scope |
Advanced manufacturing continues to improve the efficiency, capability, and cost effectiveness of developing new technologies and bringing them to market, accomplished largely as a result of advanced computational tools (e.g., Integrated Computational Materials Engineering, ICME) and automation of manufacturing processes. These advances, along with dramatically different materials processing conditions of modern fabrication techniques compared to traditional casting and forging operations have necessitated the development of new materials, and highly accurate physics-based models of the relationships between material chemistry, processing, and microstructure (and properties), which are most often grounded in fundamental thermodynamic and kinetic principles. This presentation explores some recent advances in such modeling tools, focused particularly on how chemistry and processing conditions affect solidification microstructure and subsequent solid-state phase transformations. Specifically, the connection of solidification models, broadly categorized as interface response functions to material response and microstructural development during additive manufacturing are discussed. |
