Effect of Al-ZrB2-TiC binder systems on microstructure, and mechanical properties of PcBN composites

Key Points

• Changes in mechanical properties correspond to variations in binder systems and microstructure.
• The analysis shows an increase in toughness by up to 30% with specific binder formulations.
• Assessment using microstructural analysis highlights the importance of TiC and ZrB2 in binder composition.
• These findings suggest that optimizing binder systems could enhance industrial applications of PcBN composites.
