The uniphase C with W/≤0.3 can be synthesized without being preheated. When W/ is higher than 0.3, the sample expansion increases with the increase of W content, the reaction between W and C is incomplete, the combustion products consist of W〓C, WC, TiC, C, and unreacted W. Preheating mixtures can accelerate the completion of the reaction among Ti, W, and C. The uniphase C with W/=0.4 can be synthesized by SHS at preheat temperature of 600℃. There are two kinds of powders with size of 2-4μm and size less than 1μm in the combustion products.

通过燃烧前沿激冷淬熄试验及产物形貌特征（燃烧块断面组织和产物多晶聚合体颗粒）分析，创新性地提出了两种体系的自蔓延高温反应机制。1熔化—溶解—析出机制：当燃烧温度较高时，燃烧前沿Ti粉熔化，W和C溶解于熔融Ti里，而后C从熔融里析出。2扩散—固溶机制：当燃烧温度不足以使燃烧前沿Ti粉熔化时，通过C的扩散先形成TiC层，其后C沿着热应力导致的TiC层裂纹继续扩散，与固态Ti核反应生成TiC；同时，C扩散至W颗粒，形成W〓C，而后通过C的继续扩散W〓C转变成WC；与此同时，WC固溶至TiC里，形成C固溶体。

The computational results indicate that surface catalytic combustion restrains gas phase combustion. Inlet velocity and tube diameters have important influence on catalytic combustion of hydrogen. For smaller inlet velocities,reaction is dominated by gas phase combustion. As the inlet velocity increases,there exist both surface catalytic combustion and gas phase combustion. For bigger inlet velocities,reaction is dominated by surface catalytic combustion. The temperature of flame core decreases with the decrease of tube diameter.

计算结果表明，表面催化反应对空间气相反应有抑制作用；入口速度和管径对氢气的催化燃烧过程有重要的影响，在入口速度较小时，燃烧主要是空间气相化学反应，随着入口速度的增大，燃烧过程同时存在着表面催化反应和空间气相反应两种控制因素，在入口速度较大时，燃烧主要是表面催化燃烧过程；随着管径的减小，微型管道内反应的最高温度降低。
