DESCRIPTION:Dr. Bernd Gludovatz\, Lawrence Berkeley National Laboratory\, 
 USA\nBio: Bernd Gludovatz is currently a post-doctoral fellow of Prof. Rob
 ert O. Ritchie at the Materials Sciences Division of the Lawrence Berkeley
  National Laboratory. He received his M.S. and his Ph.D. as a student of P
 rof. Reinhard Pippan at the University of Leoben\, Austria\, both in Mater
 ials Science and Engineering. His research interests are in the mechanical
  behavior of structural materials\, particularly fracture and fatigue of a
 dvanced metallic alloys\, nature-inspired ceramic composites and biomateri
 als.\nAbstract :\nDamage tolerant materials with a good combination of tou
 ghness and strength are a long sought after goal for both mechanical engin
 eers and materials scientists. Unfortunately\, these properties are genera
 lly mutually exclusive and the development of new alloys with damage toler
 ant design has traditionally been a compromise between hardness and ductil
 ity. This talk will focus on recently developed advanced metallic alloys t
 hat show a good combination of both strength and toughness\, bulk-metallic
  glasses (BMGs) and high-entropy alloys (HEAs). Strength levels often well
  above 2 GPa\, fracture toughness values up to 200 MPa.m1/2\, and fa-tigue
  limits up to 25% of the ultimate tensile strength make BMGs promising can
 didates for many structural applications. High-entropy alloys\, on the oth
 er end\, have strengths above 1 GPa and fracture toughness values well abo
 ve 200 MPa.m1/2. Interestingly\, their properties can improve with decreas
 ing temperatures – a trend that is the opposite for most other mate-rial
 s.
