Energy deposition at the interface of the particles caused by micro-explosive welding in explosive consolidation of metal powders is analyzed by symmetrical impaction model of uncompressible liquid. Two-dimensional equation of energy in the flow field of explosive welding is deduced and solved by finite difference method. Then the distribution of the temperature in the flow field is calculated on the basis of considering the adiabatic compression.

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。
