International Excellence Talks
Excellence lives on exchange and networking among the best researchers worldwide. That is why we want to invite you to join us in a new lecture series, International Excellence Talks, where internationally renowned scientists will give insights into their current research topics and, ideally, inspire a broad audience of scholars. This monthly event will include a 30-minute keynote lecture and a platform for networking and informal exchange among researchers with a wide range of interests. Recordings of previous talks can be found on the KIT International Excellence Talks YouTube Channel.
The next Talk: "Exploring the Limits of Metals Strength" with Prof. Dr. Rabkin
The fourth International Excellence Talk will be hosted by the Institute for Applied Materials (IAM) with Prof. Dr. Eugen Rabkin on the topic "Exploring the Limits of Metals Strength" on Thursday, 23 September 2021 at 5:00 PM. We are glad to inform you that this talk will be the first one held as an attendance event.
Prof. Dr. Eugen Rabkin
- Professor, Trudy and Norman Louis Chair in Engineering, Department of Materials Science and Engineering at Technion - Israel Institute of Technology, Haifa, Israel
- Research Topic: Mechanisms of Dislocations Nucleation in Metal Nanoparticles
- International Excellence Fellow of KIT (August-September 2021)
- Host Institute: IAM - Materials- and Biomechanics
In his talk, Prof. Dr. Rabkin will present his insights on mechanical strength of elemental metals and alloys. More specifically, his group has studied the uniaxial compression behavior of micro- and nanoparticles of several elemental metals (Au, Ni, Ag, Mo, Pt) and alloys (Ni-Fe, Ni-Co, Au-Ag). The particles were obtained by solid state dewetting of thin metal films and multilayers deposited on hard substrates. The record-breaking compression strength of the particles (i.e. 46 GPa for Mo) and counterintuitive solid solution weakening were observed and correlated with the nucleation of dislocations – linear defects responsible for metals plasticity. The observed values of strength put metals on par with the strongest materials such as diamond or carbon nanotubes.
