| 摘 要： | 对ＳｉＣ粉末的爆炸绕结过程进行了数值模拟，计算了粉末中入射冲击波和反射冲击波压力；与实验测得的压力峰值吻合良好，从计算结果出发，讨论了ＳｉＣ粉末烧结中裂纹形成的机制。

| Abstract: | The numerical simulations on dynamic compaction of SiC powder have been performed, calculating the incident and reflected shock pressure in powder, which is well consistent with peak value measured by experiments. On the basis of calculated results, the mechanism of cracks formation in SiC powder compact is discussed. |
