对ＳＨＳ法制备ＴｉＢ２－ｘＦｅ系统复合材料进行了热力学计算，得到了绝热燃烧温度同金属稀释剂含量、绝热燃烧温度同反应预热温度等关系。依据热力学计算的结果对ＳＨＳ合成ＴｉＢ２－ｘＦｅ系统的过程机理进行了预测，并运用实验结果加以验证。
The thermodynamic calculation of TiB2-xFe system composite prepared by SHS method was carried out, and the relationship between adiabatic combustion temperature and metal diluent content, adiabatic combustion temperature and reaction preheating temperature were obtained. Based on the results of thermodynamic calculation, the mechanism of synthesis of TiB2-xFe system by SHS was predicted and verified by experimental results.
