  • Topic: Lectures
Severe plastic deformation is a well-established method for producing nanocrystalline and ultrafine-grained materials. Among severe plastic deformation techniques, high-pressure torsion (HPT) is particularly versatile. In addition to deforming bulk materials, HPT can be used for mixing ... [more]

Grain boundary stabilization: thermodynamics or kinetics?

  • Date: Jul 21, 2026
  • Time: 11:00 AM - 12:00 PM (Local Time Germany)
  • Speaker: Prof. Yuri Mishin
  • Humboldt Research Award Winner 2026; George Mason University, USA
  • Location: Max Planck Institute for Sustainable Materials
  • Room: Large Conference Room No. 203
  • Host: on invitation of Prof. Gerhard Dehm
Two approaches have been proposed to slow down grain growth in nanocrystalline materials: the thermodynamic approach, which aims to reduce the grain boundary (GB) free energy, and the kinetic approach, which seeks to reduce GB mobility. Both approaches rely on GB segregation. We argue that the two ... [more]
