Qualification frameworks and ICME for metal AM across multiple processes
Suresh Babu is UT-ORNL Governor's Chair in Advanced Manufacturing, jointly appointed at the University of Tennessee Knoxville and Oak Ridge National Lab, and a leading figure in qualification and integrated computational materials engineering (ICME) for metal AM. With colleagues at ORNL he co-authored the 2016 International Materials Reviews paper "The metallurgy and processing science of metal additive manufacturing" (sames-2016-metallurgy), which mapped the rapid thermal cycles in LPBF, EBM, and DED to the resulting columnar grain growth, texture, and anisotropy. His group at ORNL also led the seminal EBM IN718 work (sames-2014-in718-ebm) that explained heterogeneous phase distribution in EBM builds via the three-stage thermal cycle model. Babu has helped develop AM qualification frameworks adopted by ASTM F42, AWS, and the AMS additive committees, and directs the Bredesen Center for interdisciplinary research at UTK. His work spans laser, electron-beam, arc, and binder-jet processes for steels, nickel superalloys, and titanium.
