| 摘 要： | 研究了冲击波作用下Al-C、Al-Si和Si-C三种粉体的细化与均化情况。结果表明，冲击波对微米级粉体有明显的细化和均化作用，各组分的细化程度与其晶体结构和力学特性有关，其中，冲击波作用后的Si-C粉体粒度达到300 nm以下。

| Abstract: | The grain size refinement and homogenization of Al C,Al Si and Si C powders after shock loading were studied.Experimental results show that shock wave propagation in powders resulted in significantly grain size reduction and homogenization of micron powders.The extent of grain size reduction of one component is related to its crystal structure and mechanical properties.The grain size of shock treated Si C powder is smaller than 300nm.
