| Abstract Scope |
Models are reported for L-PBF of metallic alloys for industry. They include M1- phase transformations with rapid solidification phenomena at phase interfaces, M2- thermohydraulic prediction of the melt pool and bead geometry due to laser processing, M3- prediction of the grain structure and its crystallographic and morphological textures, M4- thermomechanical analysis at the scale of a component while printing.
These modeling approaches are usually successively chained through a weak coupling scheme, M1->M2 and/or M2->M3, while the computed grain structure under construction is not accounted for at the scale of the component, M3-//->M4.
We will review efforts to go beyond such successively weakly coupled schemes. The goal is to determine the role of the microstructure under formation on the melt pool geometry and the solidification path as well as on thermomechanical loading at bead and part scale. |
