为研究TiB2/CuZr 复合材料的增强相在CuZr 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AlTiB2O3 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CuZr 熔体中制备了TiB2/CuZr 复合材料。
In order to study the thermodynamic conditions of TiB2 / Cu-Zr composite reinforced phase formed in CuZr matrix, the reaction thermodynamics of AlTiB2O3 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.
