高温高压下单质炸药结构演化的研究进展

The safety performance and initiation process of explosives are closely related to their high‑temperature and high‑pressure behavior. Therefore, it is of great significance to study explosives under high‑temperature and high‑pressure thus understanding their safety and initiation performance in depth. The structural evolution of twelve explosives under high‑temperature and high‑pressure is reviewed, including common nitroamine‑based explosives represented by RDX and HMX, common nitroester⁃based explosives represented by PETN, nitro⁃based explosives represented by TNT, and new high‑energy and low‑sensitivity explosives represented by LLM‑105 and TKX‑50. The phase transformation processes of these explosives under high‑temperature and high‑pressure are summarized in detail, and the similarities and differences of the research results from different research teams on the same material are compared. This review provides a strong basis for the studies of structural evolution of explosives under high‑temperature and high‑pressure.
