英文摘要	The densification and mechanical properties of B4C–TiB2composites fabricated by reactive pulsed electric current sintering from a mixture of TiC and amorphous B powders were investigated. The excess of B was essential to remove the carbon produced by the reaction. The degassing process at 1900 °C before applying a 50 MPa external pressure greatly improved the densification of the composites. The B4C–41 vol% TiB2composite obtained at the optimum condition had a high 3-point bending strength of 891 MPa, a Vickers hardness of 28 GPa and a fracture toughness of 4.4 MPa m1/2, respectively. © 2017 Acta Materialia Inc.
