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.

M7C3: Unveiling the structure of a misunderstood carbide

By Lisa McDonald / August 26, 2022

The use of data-driven methods to tailor the growth characteristics, stability, and mechanical properties of M7C3-type carbides is hindered by ambiguity surrounding the carbide’s structure. To overcome this uncertainty, researchers from the United States and Israel used a variety of imaging techniques to reveal the atomistic structure of M7C3 carbides.

Designing better ballistic materials: Reduced processing costs, higher toughness, and microstructural cues

By Jonathon Foreman / March 23, 2021

Designing better ballistic materials is more than a matter of finding the optimal combination of material properties—a deep understanding of the microstructure–damage relationships is required as well. A number of recent articles published in ACerS journals look to improve processing methods for fabricating dense, resilient ceramic components.
