SUMMARY:Space Seminar: Space Seminar: High Entropy Alloys – Cutting-Edge Materials for Space Applications
DESCRIPTION:Details\n\n 	Date: May 13, 2026  	Time: 15:00  	Location: Build
 ing D3, Room 1.05  \n\nThe seminar will be held on-site. Participants who a
 re unable to attend in person are welcome to join online via MS Teams\n\nAb
 out the Speaker\n\nProfessor Marek Dollar received his academic training at
  AGH University of Krakow (MS, PhD, DSc, and professorship). He has recentl
 y joined the Faculty of Space Technologies at his alma mater after a distin
 guished 40-year career in the United States. His experience includes positi
 ons at Carnegie Mellon University, Illinois Institute of Technology (where 
 he served as Professor and founding Chair of the Department of Mechanical, 
 Materials & Aerospace Engineering), and Miami University in Ohio (as Prorec
 tor and Founding Dean of the College of Engineering & Computing). \n\nProf.
  Dollar has an outstanding research record in materials science, particular
 ly in understanding structure–property relationships in high-temperature st
 ructural materials for aerospace applications. His current research focuses
  on ultra-high-temperature, multifunctional materials designed for extreme 
 conditions in outer space. \n\nAbout the Seminar\n\nHigh-entropy alloys (HE
 As) have emerged as a transformative class of metallic materials with excep
 tional potential for extreme space environments. Unlike conventional alloys
  based on one principal element, HEAs consist of multiple principal element
 s in near-equiatomic proportions. This unique composition leads to high con
 figurational entropy, significant lattice distortions, and sluggish diffusi
 on, resulting in remarkable combinations of strength, ductility, thermal st
 ability, and radiation tolerance. \n\nThis seminar explores the scientific 
 foundations and engineering potential of HEAs for space applications, with 
 particular emphasis on refractory HEAs for ultra-high-temperature service. 
 The mechanical behavior of these alloys will be discussed and compared with
  nickel-based superalloys currently used in aerospace systems.
