Abstract<\/h2>\n\n\n\n

High-entropy oxides (HEOs) offer promising structural performance due to their compositional complexity and stable single-phase structures. This study investigates the mechanical behavior of spark plasma sintered (Co, Cu, Mg, Ni, Zn) O using\u00a0in situ<\/em>micropillar compression from room temperature to 600 \u00b0C inside a scanning electron microscope, complemented by transmission electron microscopy and crystallographic orientation mapping. At room temperature, brittle transgranular fracture occurs with limited dislocation activity. At 400 \u00b0C, shear localization, Cu-rich secondary phases and delayed cracking emerge. At 600 \u00b0C, prominent plastic deformation is observed accompanied with work hardening. Microscopy studies reveal dislocation glide, slip band formation, grain fragmentation, and Cu-rich secondary phases. This study confirms temperature-dependent plasticity in (Co, Cu, Mg, Ni, Zn) O and demonstrates the potential of entropy-stabilized design in overcoming ceramic brittleness via microstructural engineering.<\/p>\n","protected":false},"excerpt":{"rendered":"
