Materials Genome Initiative (MGI)

Closeout Summary: The objectives of this project element were to apply computational methods in conjunction with experimental characterization and processing studies to gain a better understanding of manufacturing processes and materials behavior to accelerate process development and certification to more efficiently integrate new materials into existing and future NASA missions and lead to the design of new materials for improved performance. Specifically, the MGI project element focused on applying this approach to the Selective Laser Manufacturing of engine components for the Space Launch System and also sought to leverage investments and activities of other Federal agencies participating in the Materials Genome Initiative. This project developed and experimentally validated thermal models of SLM manufactured components to predict residual stresses and distortion and developed a process control tool for SLM fabrication of engine components and delivered it to the SLS Program. Computational tools developed under the MGI Project Element will also be transitioned into the GCD Rapid Analysis and Manufacturing Propulsion Technology (RAMPT) Project for further development
