MA 6: Focus: Dislocations in Ceramics: Mechanics, Structures and Functionality (joint session KFM/MA)

Montag, 27. März 2023, 14:30–17:05, POT 51

Contrasting the common (mis)belief that ceramics are brittle, a new horizon of dislocation engineering in ceramics is being revealed, where dislocations are used to harness the mechanical and electro-functional properties. This session will bring together researchers who are interested in dislocations in ceramics, covering experiments and simulations, to stimulate new ideas for dislocation-based mechanics, characterization, and functionality in ceramics.

Chair: Dr. Xufei Fang (TU Darmstadt), Dr. Till Frömling (TU Darmstadt)
