|As the metal Additive Manufacturing (AM) technology evolves and becomes a viable option for actual component production, a better understanding of the fundamentals and particularities associated with phase transformations involving both, liquid and solid, during the printing process, post-processing and service of additive manufactured materials becomes extremely important. The differentiated microstructures associated with AM and their relationship with the materials and components performance can only be fully understood, modeled and engineered if the phase transformations that have been involved on their formation and evolution are adequately understood. Therefore, this symposium will bring together both the phase transformations and additive manufacturing communities to address fundamental and applied aspects of phase transformations on additive manufactured materials. The topics of interest include, but are not limited to:
• Solidification and liquation phenomena, including the resultant chemical segregation;
• Solid state transformations during the printing, post-processing and service of metallic materials;
• Effects of segregation profiles, impurities content and distribution, crystallographic texture, and residual stresses on liquid-solid and solid-solid phase transformations;
• Relationships between phase transformations and defect formation during additive manufacturing and the use of fundamental understanding to propose engineering solutions;
• Modeling and simulation of phase transformations associated to AM and AM materials;
• Interdependence of thermo-mechanical conditions and phase transformations on the microstructural evolution and final materials performance;
• The use of conventional and advance phase transformation models on the design and optimization of alloys better suited for different AM processes.
