Scientific communities struggle with the challenge of effectively and efficiently sharing content and data. An online portal provides a valuable space for scientific communities to discuss challenges and collate scientific results. Examples of such portals include the Micromagnetic Modeling Group (μMAG [1]), the Interatomic Potentials Repository (IPR [2, 3]) and on a larger scale the NIH Genetic Sequence Database (GenBank [4]).

- This study employs numerical simulations to analyze microstructure and microsegregation during the rapid solidification of a Ni-based superalloy (Inconel 625) in laser powder bed fusion additive manufacturing.
- Finite element analysis is used to model the laser melt pool, aligning surface temperature results with thermographic data, and subsequently informs mesoscale simulations for solidification phenomena.
- The research contrasts microsegregation predictions from the Scheil-Gulliver model and DICTRA software with experimental microstructures, also evaluating precipitate formation in relation to thermodynamic driving forces at various heat treatment temperatures.
