Abstract:

炸药件的膨胀特性对其使用性能有重要影响,研究TATB基PBX炸药件晶体取向与膨胀特性的关系,可为控制TATB晶体的形稳性提供基础支撑。采用线膨胀仪测定了颗粒状、片状及原材料TATB晶体所压制药柱沿不同方向的膨胀特性,采用X射线衍射仪和Rietveld全谱拟合精修的方法测定了TATB基PBX炸药件的晶体取向(F),并研究了TATB晶体取向对膨胀特性的影响。结果表明:TATB基PBX药柱存在各向异性膨胀,轴向的膨胀程度约为径向的2倍,膨胀系数(αCTE)与药柱中晶体的取向满足关系αCTE=(7.08+10.37×F)×10-5K-1,药柱的线膨胀系数随晶体取向增大而增大,而不同形貌的TATB晶体所压药柱的取向不同。因此,通过改变晶体形貌可以控制晶体取向,进而抑制药柱膨胀的各向异性,改善TATB炸药的形稳性。
