a, b The surface crack propagation path in Gd2Zr2O7 and HEPO samples; c Straight and brittle crack propagation in Gd2Zr2O7 crystal; d Crack bridging in HEPO interacting with two edge dislocations; e Crack deflection in HEPO interacting with two edge dislocations. Dislocations are indicated by red arrows. The color scale denotes the coordination number of each cation (unit: counts).
