| 摘 要： | 环三亚甲基三硝胺(RDX)、环四亚甲基四硝胺(HMX)和六硝基六氮杂异伍兹烷(CL-20)三种多晶型含能材料在高压/高温高压下具有丰富的相变行为及相变特征,本文总结了三种炸药在不同压力环境下的相变路径、部分相结构及p-T相图,为含能材料的爆轰行为和理论研究工作提供参考。根据目前的研究现状,发现在较复杂的相变研究上仍存在分歧,大部分高压相的结构还不明确,p-T相图不够完善,相变理论的研究也存在明显不足。指出探索含能材料的不同晶型间转化机理和获取更多相结构信息将是未来的重点研究方向。

| Abstract: | Cyclotrimethylenetrinitramine (RDX), Cyclotetramethylenetetranitramine (HMX) and Hexanitrohexaazaisowurtzitane (CL-20) own abundant phase transition behavior and characteristics under high pressure/high-temperature and high-pressure. The phase transition routes of three high explosives under different conditions, part of the phase structures under high pressure and p-T phase diagrams were summarized. These researches have provided effective references for the study of detonation behavior and theoretical analysis of energetic materials. Based on current works, there still exist some problems in this area. For example, some divergences still exist about the study of the complex phase transitions, most of the new structures under high pressure are not confirmed and the p-T diagrams are incomplete. In addition, the profound theoretical mechanism of the phase transition has not been sufficiently revealed. Therefore, it will serve as a main tendency to explore the mechanism of transformation between different crystal phases and obtain more information of phase structures in the future research. |
