DESCRIPTION:Dr. Stoichko Antonov from Structural Materials Team at National
  Energy Technology Laboratory (NETL) will give a seminar titled "Designing
  Next-Generation Structural Materials: From Concept to Scale-Up" to the in
 terested faculty and students at Discovery Park.\n\n \n\nAbstract\n\nIncre
 asingly demanding operating conditions associated with highly efficient en
 ergy systems\, especially those fueled by hydrogen\, require enhanced cree
 p capability\, fatigue resistance (especially against damage from increase
 d cycling)\, and corrosion/oxidation from the environment. Consequently\, 
 innovative approaches are needed to design alloys\, relying on a critical 
 combination of chemistry and a microstructural blueprint of features for s
 tability and strength. This talk will focus on the team’s efforts to imp
 rove existing commercial and NETL developed alloys as well as to develop a
 ffordable\, durable\, cost-effective high-performance materials (HPMs) nec
 essary for safe and reliable generation of power from hydrogen and enablin
 g a bridge to net-zero carbon economy. Specifically work on the NETL 725 v
 ariants\, which contain γ′/γ″ compact precipitates\; the NETL 740H c
 asting process to produce a 740H castings with creep lives similar to the 
 wrought product\; as well as NETL’s advanced Fe-9% Cr martensitic-ferrit
 ic steel (CPJ7). Our team has demonstrated scale-up a variety of experimen
 tal alloys from ~6.8 kg to ~68 kg by VIM and ESR. These High-quality indus
 trial-scale ingots are often made by ESR\, including mission critical heat
 -resistant alloys for advanced energy systems. In addition\, a brief summa
 ry of NETL’s new programs on designing alloys for hydrogen service will 
 be presented.\n\n \n\nBiography\n\nDr. Stoichko Antonov received his Ph.D.
  the from Illinois Institute of Technology in 2017\, working on alloy desi
 gn and development of Ni-based superalloys. Between 2017 and 2019\, he was
  a research assistant professor at the University of Science and Technolog
 y in Beijing. His research is mainly focused on solving energy sustainabil
 ity and manufacturing challenges in the air transportation industry by lev
 eraging knowledge on the physical metallurgy of aerospace materials (super
 alloys\, steels and titanium alloys). He is the recipient an 2020/2021 Ale
 xander von Humboldt fellowship and was hosted by the Max-Planck-Institut f
 ür Eisenforschung in Germany where he held the deputy group leader positi
 ons of the Atom Probe Tomography and High-Performance Materials for Extrem
 e Environments groups. His research efforts were aimed at utilizing advanc
 ed multi-scale characterization methods\, such as atom probe tomography (A
 PT) and transmission electron microscopy (TEM) correlatively\, to link the
  near-atomic scale (phase transformations) processes to the macro-scale (d
 eformation mechanisms) behavior of different advanced Ni-\, Ti-\, and Fe- 
 alloys\, especially in the presence of defects and atomic hydrogen. Along 
 this path he has also worked on developing experimental workflows that ena
 ble characterization of environmentally sensitive materials\, e.g. hydroge
 nated Ti and battery anodes\, via cryogenic sample preparation. He has aut
 hored and co-authored more than 70 peer-reviewed papers.
