DESCRIPTION:In modern society\, metallic materials are crucially important 
 (e.g. for applications related to energy\, safety\, infrastructure\, trans
 portation\, health\, medicine\, life sciences\, IT). Contemporary examples
  with inherent challenges to be overcome are the design of ultrahigh speci
 fic strength materials. There is a critical need for successful developmen
 ts in this area in particular for reduced energy consumption\, reduction o
 f pollutant emissions and passenger safety. Also\, the ageing society make
 s biomedical materials for implant and stent design crucially important. A
  drawback of nearly all current high strength metallic materials is that t
 hey lack ductility (i.e. are brittle and hard to form) - or on the opposit
 e side\, they may be highly ductile but lack strength. Hence\, it is manda
 tory to develop new routes for creation of tailored metallic materials bas
 ed on hierarchical hybrid structures enabling property as well as function
  optimization. One starting point along these lines is the design of monol
 ithic amorphous materials or bulk micro-\, ultrafine- or nano-structured c
 omposite structures with intrinsic length-scale modulation and phase trans
 formation under highly non-equilibrium conditions. This can include the in
 corporation of dispersed phases which are close to or beyond their thermod
 ynamic and mechanical stability limit thus forming hierarchically structur
 ed hybrid and ductile/tough alloys. Alternatively\, the material itself ca
 n be designed in a manner such that it is at the verge of its thermodynami
 c/mechanical stability. This talk will present recent results obtained for
  metallic glass-based hybrid structures with transformation effects at dif
 ferent length-scales and microcrystalline-grained hybrid structures based 
 on elastic instabilities and modulated length-scale. The deformation behav
 iour and possible phase transitions during deformation will be related to 
 the intrinsic properties of the phases as well as the microstructure of th
 e material including heterogeneities and length-scale modulation in order 
 to derive guidelines for the design of macroscopically ductile high-streng
 th materials. Finally\, the results will be critically assessed from the v
 iewpoint of possible scaling-up for technological applications and the use
  of simple and cost effective processing technologies.\nSpeaker: Prof. Jü
