Mitigating crack formation—electron-rich metals increase the fracture resistance of ceramics

By Lisa McDonald / October 24, 2023

The arrangement and movement of electrons within a ceramic material has the potential to greatly influence its resistance to brittle fracture. Researchers at the University of California, San Diego and Linköping University published an open-access paper demonstrating the effect that electronic structure has on plastic deformation in high-entropy carbides.
