为研究ＴｉＢ２／ＣｕＺｒ 复合材料的增强相在ＣｕＺｒ 基体中形成的热力学条件， 采用ＤＴＡ 分析和不同温度下的热爆试验， 研究了ＡｌＴｉＢ２Ｏ３ 体系的反应热力学行为， 并讨论了其反应合成机制。结果表明： 在１１００℃下， 该体系能自动发生反应， 生成产物为ＴｉＢ２ 和少量Ａｌ２Ｏ３ ； 在较低温度反应时， 产物中存在硼化物过渡相。基于热爆工艺参数， 在ＣｕＺｒ 熔体中制备了ＴｉＢ２／ＣｕＺｒ 复合材料。 In order to study the thermodynamic conditions of TiB2 / Cu-Zr composite reinforced phase formed in CuZr matrix, the reaction thermodynamics of AlTiB2O3 system was studied by DTA analysis and thermal explosion test at different temperatures, and discussed The reaction mechanism of synthesis. The results show that at 1100 ℃, the system can react automatically to produce TiB2 and a small amount of Al2O3. At lower reaction temperature, the product has boride transition phase. Based on thermal explosion process parameters, TiB2 / Cu Zr composite was prepared in Cu Zr melt.
