Direct observation of atomic-scale fracture path within ceramic grain boundary core

Cracks propagate preferentially along grain boundaries, but what happens exactly at the atomic scale remains unclear. Here, the authors combine atomic-scale observations and first-principles calculations to show local coordination chemistry at a dopant-segregated alumina grain boundary core dictates...
