Design, Processing and Evaluation of Advanced Alloys

Date: Thursday, Apr 25th
Presenter: Dr. Paul Jablonski, National Energy Technology Laboratory


Advanced alloys provide the foundation upon which our comfortable modern life is built. They provide the means for swift and safe transportation, clean drinking water on tap, and energy that flows from the wall socket in our home, to name just a few. Continued advancements are achieved by a judicious combination of literature review, computational modeling, laboratory scale prototyping and ultimately evaluations under relevant conditions. NETL is internationally recognized for its leadership in designing, developing, and deploying advanced materials for use in energy and other extreme service applications. Of particular note is NETL’s ability to design, engineer, and evaluate materials at size and time regimes ranging from atomistic to pilot-plant scales. To accomplish this, NETL utilizes a one-of-a-kind suite of computational and experimental methods for translating new material science concepts into practical technologies. Structural Materialsare being developed for use in extreme environments associated with combustion, turbine, gasification, drilling, and other applications. Research focuses on developing cost-effective materials that can withstand a combination of mechanical stress, and corrosive and erosive environments for upwards of 100,000 hours of service life. This is accomplished through improving existing alloys, designing new materials, and reducing manufacturing cost. Research also investigates corrosion, wear, hot-corrosion, oxidation, creep, and fatigue resistance. Expanding the knowledge base on these topics will enable researchers to develop materials that resist degradation in severe service environments and new models for service life predictions. Research facilities include capabilities for fatigue and creep testing; facilities for melting, casting, forging, rolling, and heat-treating materials from a few grams to over 100 kilograms. In this talk we will give examples of successes as well as failures experienced in the lab including developing new materials for specific applications including medical devices and power plant components.

Dr. Paul D. Jablonski, Senior Metallurgist, National Energy Technology Laboratory, has been at the Albany facility for nearly twenty years. He has an undergraduate (B.S.) from Michigan Technological University and a graduate degree (Ph.D.) from the University of Wisconsin-Madison, both in Metallurgical Engineering. He has over 35 years’ experience in metals including alloy design of Ni-based, Fe-based, Co-based, Cu-based, Al-based and Ti-based alloys ranging from melting, hot and cold working to post processing evaluation. Some notable work includes a biomedical stent alloy currently used throughout the world with multi-billion dollar sales annually and a computational approach to alloy homogenization responsible for 2-3x improvement in life for advanced alloys in fossil energy applications. Author/coauthor on more than 80 publications and over 200 formal presentations, more than 40 proprietary reports, eight patents granted, several more under review, four R and D 100 awards, the Secretary of Energy Achievement award, Carnegie Science Award—Advanced Materials, the Arthur S. Flemming Award and a Fellow of ASM.
