研究了冲击波作用下Al -C、Al-Si 和S i-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300nm以下。
研究瞭遲擊波作用下Al -C、Al-Si 和S i-C三種粉體的細化與均化情況。結果錶明，遲擊波對微米級粉體有明顯的細化和均化作 用 ，各組分的細化程度與其晶體結構和力學特性有關，其中，遲擊波作用後的Si-C粉體粒 度達到300nm以下。
연구료충격파작용하Al -C、Al-Si 화S i-C삼충분체적세화여균화정황。결과표명，충격파대미미급분체유명현적세화화균화작 용 ，각조분적세화정도여기정체결구화역학특성유관，기중，충격파작용후적Si-C분체립 도체도300nm이하。
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.
