Symposium Dislocations in Ceramics: Processing, Structure, Mechanics, and Functionality
Presentation Title Conceptual Framework for Dislocation Mechanics in Ceramics
Author(s) Lukas Porz
On-Site Speaker (Planned) Lukas Porz
Abstract Scope Dislocations in ceramics have been studied from various perspectives over the decades with a current wave of renewed interest. Advances in imaging methods, computing and fabrication approaches foreshadow great potential to understand and exploit their effect on a series of functional properties in the near future. However, a cohesive perspective on their mechanical behavior across single and polycrystals of various crystal structures is still missing. Unfortunately, there is no such thing as a role model ceramic in this context, as there are aluminum and fcc/bcc iron for metals. Moreover, the numerous valuable pieces of knowledge are spread across materials, decades and disciplines. In this presentation, I rise awareness to all the components involved in dislocation mechanics in ceramic by sorting them into five steps to consider and by fitting ceramics in a concept established for metals. This conceptual framework now alerts to blind sports and cross counterintuitive cross-relations.
