英文摘要Titanium carbide ceramics with different contents of boron or B4C were pressureless sintered at temperatures from 2100 degrees C to 2300 degrees C. Due to the removal of oxide impurities, the onset temperature for TiC grain growth was lowered to 2100 degrees C and near fully dense (>98%) TiC ceramics were obtained at 2200 degrees C. TiB2 platelets and graphite flakes were formed during sintering process. They retard TiC grains from fast growth and reduced the entrapped pores in TiC grains. Therefore, TiC doped with boron or B4C could achieve higher relative density (>99.5%) than pure TiC (96.67%) at 2300 degrees C. Mechanical properties including Vickers' hardness, fracture toughness and flexural strength were investigated. Highest fracture toughness (4.79 +/- 0.50 MPa m(1/2)) and flexural strength (552.6 +/- 23.1 MPa) have been obtained when TiC mixed with B4C by the mass ratio of 100:5.11. The main toughening mechanisms include crack deflection and pull-out of TiB2 platelets. (C) 2016 Elsevier Ltd. All rights reserved.
