Strengthening and Toughening of B4C-TiB2 Multiphase Ceramics

Abstract

Abstract: B₄C-TiB₂ composites were prepared by hot-pressing process at 2050°C. The effects of TiB₂ particlecontent on the fracture toughness, bending strength and Vickers hardness of B₄C-TiB₂ composites werestudied. The addition of 3Ovol% TiB₂ raised the bending strength of B₄C to the peak value of 725MPa, 65%higher than monolithic B₄C. An 84% increase of composite toughness up to 6.7MP.m^1/2 was discoveredupon the incorporation of 45vol% TiB₂ particles into B₄C matrix. The crack deflection caused by theresidual stress resulting from the difference in thermal expansion coefficient between B₄C and TiB₂ is the main mechanism responsible for the increase of toughness.

Key words: B₄C, TiB₂, strengthening and toughening, crack deflection
