摘　　要：传统铝热剂具有较高的反应焓,但较慢的能量释放速率和较低的能量转化效率严重限制了其应用范围。超级铝热剂,即亚稳态分子间复合材料(MIC)的出现,很好地解决了这一问题。在众多MIC的制备方法中,反应抑制球磨(ARM)法优势明显。综述了ARM法制备MIC的最新研究进展,对现有的MIC体系种类进行了总结,并分析了制备过程中工艺参数和环境条件对MIC产物结构和性质(包括热性能、燃烧性能和力学性能)的影响;指出了现有的MIC球磨模型和燃烧模型的局限性,并对今后ARM法制备MIC的研究方向和研究重点进行了展望。Traditional thermite has high enthalpy of reaction, but its slower energy releasing rate and lower energy transforming efficiency restrict its application fields. The appearance of super thermite, i. e. the metastable intermoleeular composite（MIC） , resolves this problem successfully. Compared with other preparation methods of MIC, the arrested reactive milling （ARM） has many apparent advantages. Current progress in MIC prepared by ARM is reviewed. The kinds of MIC formulation up to now are summarized. The influence of processing parameters and ambient conditions on the structure and properties of MIC is analyzed systematically. The limitations of milling model and combustion model about MIC are pointed out. In addition, the future research direetion and focus of MIC prepared by ARM are suggested.
