Dynamic Behaviors of RDX Single Crystal under Ramp Wave Compression up to 35 GPa

Institute of Fluid Physics, CAEP, Mianyang 621999, Sichuan, China

摘要

摘要: 利用磁驱动斜波加载10 MA装置和激光干涉测速技术，开展了35 GPa压力下(100)晶向RDX单晶炸药的斜波压缩实验，获得了RDX单晶/LiF单晶窗口界面速度数据。实验结果显示，速度波剖面表现为明显的三波结构，由低到高依次对应弹性波、塑性波和相变波，α-γ相变的起始压力为3.1 GPa。结合修正的多相状态方程和非平衡相变动力学模型，对RDX单晶炸药的斜波压缩过程开展一维流体动力学数值模拟，模拟结果与实验结果基本一致。

Abstract: A ramp wave compression experiment of (100) RDX single crystal under 35 GPa was carried out with the magnetic driven 10 MA device and laser interferometry, and then the interface velocity data of RDX single crystal/LiF window were obtained. The experimental results show that the velocity wave profile shows a three wave structure, which corresponds to elastic wave, plastic wave and phase transition wave from low to high pressure. The onset pressure of α-γ phase transition is 3.1 GPa. One dimensional hydro-dynamic simulation of ramp wave compression process of RDX single crystal was also carried out by combining the modified Hayes multi-phase equation of state and non-equilibrium phase transformation dynamic model. The calculated and experimental data are basically consistent.
