Design strategy of phase and microstructure of Si3N4 ceramics with simultaneously high hardness and toughness

Aiming to achieve silicon nitride (Si3N4) ceramics with high hardness and high toughness, the relationships among phase composition, microstructure, and mechanical properties of Si3N4 ceramics prepared by spark plasma sintering (SPS) at temperatures ranging from 1500 to 1800 ℃ were investigated in t...
