Abstract

Carbon nanotubes (CNTs)–TiB 2 –Ni composites with improved mechanical properties were fabricated by hot pressing at 1600°C/30 MPa/1 h. The effects of CNTs content on the microstructural feature and mechanical properties were investigated. The incorporation of multiwall carbon nanotubes (MWNTs) could significantly improve the mechanical properties of the TiB 2 cermet matrix composites. The main toughening mechanisms include CNTs pulling‐out, crack deflexion, bridging, and CNTs rupture.
