摘要
用真空热爆加压工艺制备了高颗粒含量的 Ｔｉ Ｃｐ ／２０２４ 复合材料， 通过数据采集器记录了不同铝含量时热爆反应的时间温度曲线； 通过 Ｘ Ｒ Ｄ 分析了 Ｔｉ Ｃｐ ／２０２４ 复合材料的相组成； 用扫描电镜分析了 Ｔｉ Ｃｐ的分布和形貌。结果表明： 随着 Ａｌ含量的增加， 起始反应时间延长， 最高反应温度和反应速度降低。当 Ａｌ含量小于 ６５ｗ ｔ％ 时反应生成 Ｔｉ Ｃｐ ， 当 Ａｌ含量大于 ６５ｗ ｔ％ 时除了反应生成 Ｔｉ Ｃｐ 外， 还存在 Ｔｉ Ａｌ３ 相。
The TiC p/2024 Composites with high TiC particle content were produced by vacuum thermal explosion and pressure process The curves of temperature vs time were recorded by data collection instrument The microstructure of the composites was analyzed by XRD method, and the morphology and distribution of TiC particles were observed by TEM It is shown that,with increasing Al content, the reaction time is delayed, and the maximum temperature and rate of the reaction synthesis process are reduced TiC particles are obtained under the condition of less than 65wt% Al Both TiC particle and TiAl 3 compound can be found when Al level is more than 65wt%
