"High Performance Alloys Designed Specifically for Additive Manufacturing Processes"

Current alloys used in Additive Manufacturing (AM) were originally designed to be processed via traditional metallurgy paths such as forging, and have different microstructures and properties when put through AM processes. Additionally, heat treating AM-built alloys according to standard industry practice causes material performance issues. New material chemistries designed specifically for AM processing and subsequent thermal processing steps tailored for the unique microstructures must be developed to enable AM components to reach enhanced performance. Integrated Computational Materials Engineering (ICME) technologies are effective tools to reconfigure the materials development much more quickly and at less cost than empirical trial and error methods of material development. QuesTek Innovations LLC has successfully used ICME technologies to design novel, improved alloys that are displacing materials that have been used for decades in demanding applications such as Air Force and Navy landing gear, helicopter transmissions and high performance racing. QuesTek has used ICME technologies to optimize legacy alloys and design entirely new alloys tailored specifically for AM, and to optimize post-build heat treatments across a variety of alloy systems including Al, Ti, Ni, Cu, W, Fe and stainless steel. Specific examples will be presented of US Army and US Navy-funded projects for QuesTek demonstrate (i) a Ti new alloy with 20% increase in strength over traditional Ti-6-4 in AM, (ii) a high performance carburizable steel for AM gear applications and (iii) new, printable, high strength aluminum alloys for use at room temperature and temperatures up to 325°C. 

Jason T. Sebastian, Ph.D. is the President of QuesTek Innovations LLC. QuesTek Innovations is a small business in Evanston, IL focused on the computational design, development, and insertion of new alloys and materials using Integrated Computational Materials Engineering (ICME) methodologies. Sebastian also serves on the Board of Directors of QuesTek Europe AB (Stockholm, Sweden), a joint venture company formed by QuesTek Innovations LLC and Thermo-Calc Software AB that offers ICME modelling and materials design services to the European market.

​Sebastian is a summa cum laude graduate of the University of Illinois at Urbana-Champaign where he earned a B.S. in Ceramic Engineering and a B.A. in Philosophy. After a year of postgraduate study at Cambridge University (Churchill College) with the support of a Winston Churchill Foundation Scholarship, he went on to earn a Ph.D. in Materials Science and Engineering from Northwestern University under the supervision of Prof. David Seidman and with the support of a Department of Defense National Defense Science and Engineering Graduate Fellowship.

At QuesTek, Sebastian is focused on overall company growth and management, and on the entire spectrum of commercial- and government-sponsored alloy modeling, development, and deployment activities. Since joining QuesTek in 2006, his technical activities have focused on: the development of high strength steels for structural and power transmission applications; precipitation-strengthened cobalt-based alloys; alloys for additive manufacturing; non-toxic, high-strength/low-friction copper-based alloys to replace lead-containing bronzes; a low-cost, castable titanium alloy; a highly-processable nickel-based superalloy; advanced soft magnetic alloys; and other computationally-designed alloys.

Sebastian has been the author/co-author on numerous technical papers and publications, and he holds two patents. His ASM International service includes terms as Vice-Chair (2015-2016), Chair (2016-2017), and Membership Chair (2017-2018) of the Chicago Regional Chapter, and a term as the “District 13 Representative” on the Chapter Council (2017-2018).
