| 摘 要： | 通过对快速加载后Ｃｏｍｐ．药柱剖面的扫描电镜和光学显微镜观察分析，对Ｃｏｍｐ．Ｂ炸药在快速加载下剪切带形成机理的微观机制有了初步的认识。文中采用形变试样的剖面观察分析方法，针对固体药柱这种比较软的材料，如何进行磨样、抛光、浸蚀，作了一些尝试和探索，总结出一套有效的实施办法。对不同加载速率条件下受压缩的药柱中细观组织进行了观察、分析、比较，首次给出国产Ｃｏｍｐ．Ｂ炸药装药的原始细观组织形貌，以及快速加载后药柱中细观组织形貌。经过分析，得到冲击载荷下炸药装药中绝热剪切带形成、发展的定性认识，为分析Ｃｏｍｐ．Ｂ炸药装药受冲击载荷时热点形成机理提供了一些有益的实验依据。

| Abstract: | Microstructure of Comp.B Column deformed under impact was observed with optical microscope and sweep electronic microscope. The method of polishing and etching of explosive samples deformed was given. The original microstructure pattern of domestic Comp.B and microstructure pattern of specimens deformed were shown for the first time. The Comparison of microstructure of Comp.B column deformed at different strain rate and load was made. The results of observation indicate that under impact adiabatic shear bands were found in explosive column. |
