降感RDX微观结构的X射线小角散射分析

RDX Micro-structure by Small Angle X-Ray Scattering

应用同步辐射X射线小角散射技术研究了降感RDX材料的微观结构，分析TRDX做孔数量、尺寸以及数量分布信息。结果表明降感RDX微孔尺度随样品颗粑变化不明显，数据显示微孔平均半径只有1～2nm的微弱变化。对比不同分析方法得到的微结构信息表明RDX内部除了微孔结构还存在裂缝微结构：

The micro-structure of RDX was analyzed by small angle X-ray scattering （SAXS）. The amount,scale and size distribution of pores in RDX were obtained by SAXS analysis. Results show that the magnitude of pores in the RDX samples decrease with increasing of the scales of RDX. Compared to the sample （ 〈180 um） ,the pores of the sample （ 〉420 um） decrease to about only a half. But the characteristic dimension of pores seems only have 1 -2 nm difference. The Porod analysis of RDX shows that there are not only micro-voids but also cracks structure in the RDX.
