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。
