HfN-induced phase transformation and fracture toughness improvement of α/β-Si3N4 ceramics
Key Points
Fracture toughness improved significantly, showing a rise of approximately 20% after HfN exposure.
Key evidence includes a detailed analysis of mechanical properties across multiple Si3N4 ceramic samples.
Assessment involved comparative evaluation of phase transformation and toughness metrics in two Si3N4 forms—alpha and beta.
These findings highlight the potential for utilizing HfN-enhanced Si3N4 in various industrial applications, supporting the need for further exploration.
