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。
Ti Cp / 2024 composites with high content of particles were prepared by vacuum thermal explosion-pressure process. The time-temperature curves of thermal explosion were recorded by data collector with different aluminum contents. The Ti Cp / 2024 Phase composition of composite materials; the distribution and morphology of Ti Cp were analyzed by scanning electron microscopy. The results showed that with the increase of Al content, the initial reaction time prolonged and the maximum reaction temperature and reaction rate decreased. When the Al content is less than 65w t% reaction Ti Cp, when the Al content is greater than 65w t% in addition to the reaction of Ti Cp, there TiAl3 phase.
