EFFECT OF BN/Ti RATIO ON THE REACTION SYNTHESIS OF TiB2-TiNz CERAMICS

摘要：

The effects of BN/Ti molar ratio on the self-propagating high-temperature synthesis (SHS) reaction behaviors and final products in the Ti-BN system were experimentally investigated. With an increase in the BN/Ti ratio, the combustion temperature and wave velocity first increase and then decrease with the maximum values displaying at BN/Ti=0.67. A substoichiometric TiN1-x was obtained for BN/Ti＜0.67, and a stoichiometric one was produced for BN/Ti=0.67. Moreover, the microstructure photographs of the products reveal that with the increase of the BN/Ti ratio, the grains of the ceramic phases tend to be finer.
