摘要

摘要: 结合高能球磨和高温高压实验技术，制备了块体TiN/TiB2纳米复合材料。通过X射线衍射和拉曼光谱对材料的微观结构进行了研究。结果表明，采用金属Ti和六方BN为原料，在球磨过程和高温高压实验过程中，TiN先于TiB2形成，球磨70 h后有少量的纳米晶TiN开始形成。在高温高压实验中，在样品腔的合成温度低于1 300 ℃时，没有TiB2出现；当温度达到1 300 ℃后，合成出了TiN和TiB2的复合材料。对所合成的块状材料的热膨胀性和导电性能进行了测试。

Abstract: Planetary milling and subsequent high-pressure high temperature treatment fabricated TiN/TiB2 composite materials. The structure developments of the materials were monitored by X-Ray diffraction and Raman spectrum. The mechanisms of ball milling and high-pressure high temperature treatment were researched in detail. It was found that the diffraction peaks of -TiNx appeared after milling 50 h. No self-propagating high temperature synthesis (SHS) reaction was found during the whole milling process. The sample that milled for 70 h was transformed into TiN/TiB2 composite materials after subsequent high-pressure high temperature treatment (5 GPa and 1 300 ℃).
