摘要
A pressureless sintering process using different amounts of boron carbide (B4C) as sintering aid was investigated for the densification of zirconium diboride (ZrB2). The sintering mechanism was converted from solid state sintering to liquid phase sintering as sintering temperature increased from 2150 to 2250 degrees C. B4C addition improved densification by removing the oxide impurities during solid state sintering. Besides, it could restrain the growth of ZrB2 grains. At 2250 degrees C, ZrB2 and B4C formed liquid phase which was well wetting ZrB2 grains during liquid phase sintering process. The different roles of B4C on the microstructure development, mechanical properties and oxidation resistance of the sintered ZrB2-based ceramics were investigated. (C) 2015 Elsevier Ltd.
