Experimental and theoretical studies on the nature of brittleness in composition B

摘要：

　　Melt-cast explosives often have poor mechanical properties and exhibit cracks, exudation, voids or brittleness.Especially, the exhibition of brittleness and cracks can affect the mechanical and detonation properties of melt-cast explosives based munitions, and restrain the application in high-performance weapon systems.Through nanoindentation/optical microscope testing, theoretical calculations and fracture scanning electronic microscope, the brittleness of TNT based melt-east explosive are analyzed, and other modification routes of melt-cast explosives were also summarized.Based on the analysis, we suggest some effective routes to toughen TNT melt cast explosives.
